Mojolin is self-funded How we score
Instantly is our top pick: every Outreach plan connects and warms unlimited email accounts, send limits are stated plainly, and Light Speed adds rotating dedicated IPs for very high volume. Smartlead is close behind and better for agencies that want white-label workspaces and in-app mailbox buying. Saleshandy is the best value when you also need verified prospect data, and lemlist is the pick for deep personalization with a path to LinkedIn steps. Mailshake is the cheapest start but counts email addresses per plan, which makes it a poor fit for many-inbox setups.

Instantly
A cold email platform that connects and warms unlimited sending accounts, with a lead database, AI reply handling and a built-in CRM sold alongside.
instantly.ai9.0
out of 10
Best for: Founders and outbound teams that spread volume across many mailboxes and want flat pricing that does not grow with each new inbox.
Instantly is built around the way volume senders actually work: many domains, many mailboxes, one campaign. Every Outreach plan lets you connect and warm unlimited email accounts, so the price is set by monthly sends and uploaded contacts rather than inbox count. Growth covers 5,000 emails and 1,000 contacts, Hypergrowth jumps to 125,000 emails and 25,000 contacts and adds the CRM with Unibox, and Light Speed reaches 500,000 emails with the SISR system that rotates dedicated server and IP blocks. Campaigns include advanced sequences and scheduling, A/Z testing, a global block list and bounce detection. Lead data is a separate credit plan with a 450M+ contact database, waterfall enrichment and AI writing agents, or you can buy both as a bundle. The main catch is the 1,000 contact ceiling on Growth, which most teams outgrow fast. For a founder or agency scaling across dozens of inboxes, it is the clearest fit we compared.
Standout feature
Unlimited email accounts and unlimited warmup are included on every Outreach plan, starting at $37.60 a month billed yearly.
Use cases
Founders
Spread a first outbound campaign across several new domains and warm each mailbox
Outcome: More daily volume without paying per inbox
Lead gen agencies
Run client campaigns on Light Speed with rotating dedicated IPs
Outcome: Sending reputation isolated from other senders
Outbound teams
Handle replies from every mailbox in Unibox and move leads into the CRM
Outcome: One place to work responses
Key features
- Unlimited email accounts and unlimited warmup on every Outreach plan
- 5,000 emails a month on Growth, 125,000 on Hypergrowth and 500,000 on Light Speed
- SISR system on Light Speed that assigns dedicated server and IP blocks and swaps flagged IPs
- Unibox inbox with a built-in CRM on Hypergrowth and above
- Separate credit plans for a 450M+ B2B lead database with waterfall email enrichment
Pros
- Adding mailboxes never changes the bill, which suits multi-domain sending
- Monthly email limits are stated plainly for each tier
- Outreach and lead data can be bought separately or as a bundle
Cons
- Growth caps you at 1,000 uploaded contacts
- The CRM and Unibox CRM view start on Hypergrowth
- Lead database credits are a separate subscription from sending
Rank 2 · Runner-up
Smartlead
A cold email sender with unlimited mailboxes, automatic mailbox rotation, verified prospect emails and white-label options for agencies.
smartlead.ai8.8
out of 10
Best for: Agencies and outbound teams that manage many client mailboxes and want rotation, verification and add-on infrastructure from one vendor.
Smartlead targets the same buyer as Instantly but leans harder toward agencies. All plans include unlimited email accounts, and the app rotates sending across every connected mailbox in a campaign to spread volume and protect each sender. Plans are sized by contacts, sends and verified prospect emails: Base gives 2,000 contacts and 6,000 sends, Pro 30,000 contacts and 90,000 sends, and Unlimited Smart removes the contact cap with 150,000 sends. Around the core sits a long add-on menu: SmartSenders to buy mailboxes from $3.99 a month each, SmartDelivery inbox placement tests, SmartServers with a dedicated IP at $39 per server, a dialer, and white-labeling at $29 per client workspace. That breadth is useful for an agency running many clients, but the bill can grow in several directions at once. Teams that want the cheapest entry into rotation can start on Base at $32 a month billed yearly.
Standout feature
Every plan rotates sends across unlimited connected mailboxes, with white-label client workspaces available as a $29 add-on.
Use cases
Lead gen agencies
Give each client a white-labeled workspace with its own mailboxes
Outcome: Client reporting under the agency brand
Outbound teams
Rotate a campaign across 30 connected mailboxes
Outcome: Lower volume per sender
Founders
Buy and connect new Google mailboxes through SmartSenders
Outcome: Sending infrastructure set up in one place
Key features
- Unlimited email accounts on all plans with automatic rotation across connected mailboxes
- Verified prospect emails included each month, from 2,000 on Base to 170,000 on Prime
- SmartSenders add-on to buy Google, Outlook and SMTP mailboxes inside the app
- SmartDelivery placement tests and dedicated-IP SmartServers as add-ons
- White-label client workspaces as a $29 per month add-on
Pros
- No per-mailbox fees, so rotation across dozens of inboxes costs nothing extra
- Verified emails are bundled with sending credits
- Annual billing saves 17% on every plan
Cons
- Base allows 2,000 contacts and 6,000 sends a month
- Deliverability testing and servers are extra subscriptions
- The pricing page mixes many add-ons, so totals take work to model
Rank 3 · Also great
Saleshandy
A cold outreach tool with unlimited mailboxes, multichannel sequences and a B2B database of 852M+ contacts with waterfall email finding.
saleshandy.com8.7
out of 10
Best for: Small outbound teams that want sending, prospect data and verification on one bill at a low annual price.
Saleshandy packs a lot into its entry price. Every plan connects unlimited sending mailboxes without per-inbox fees and stores unlimited prospects, with the limit applying only to contacts active in live sequences: 2,000 on Starter and 30,000 on Pro. Sends run 6,000 a month on Starter and 100,000 on Pro. Sequences can mix email, calls, LinkedIn, WhatsApp and manual tasks, and subsequences fire follow-ups based on how a prospect responds. The data side is the differentiator: a search across 852M+ contacts and 42M+ companies, with work emails found through an eight-provider waterfall and verified through ZeroBounce and BounceBan for one credit, and nothing charged when no verified email comes back. Starter includes 1,500 credits a month. The trial is short at 7 days, so plan a real test campaign before signing up.
Standout feature
One credit covers an eight-provider waterfall search and verification, and unverified results are free.
Use cases
Founders
Find verified emails for a niche list and sequence them from several mailboxes
Outcome: List building and sending in one tool
SDR teams
Trigger a subsequence when a prospect replies with interest
Outcome: Follow-up without manual sorting
Agencies
Add call and WhatsApp steps to an email-led sequence
Outcome: More touchpoints per prospect
Key features
- Unlimited email accounts with no per-inbox fees
- 6,000 emails a month on Starter and 100,000 on Pro
- Sequences with email, call, LinkedIn, WhatsApp and task steps, plus subsequences
- Search across 852M+ contacts and 42M+ companies
- Waterfall email finding across eight providers for one credit per verified email
Pros
- Lead finder credits, verification and sending share one subscription
- Unverified results cost nothing
- Unlimited prospect storage on every plan
Cons
- Starter keeps only 2,000 prospects active in live sequences
- The free trial lasts 7 days
- Phone reveals cost six credits each
Rank 4
lemlist
An outreach platform for email-led campaigns with a 650M+ lead database, AI agents and an optional multichannel tier for LinkedIn, calls and SMS.
lemlist.com8.5
out of 10
Best for: Teams that personalize heavily and want to add LinkedIn and phone steps to cold email later.
lemlist started as a personalization tool and still leads on that front, with Liquid syntax, custom text and images and AI agents that research accounts and draft messages. The Email plan covers unlimited users and email senders, 50,000 emails a month, the 650M+ lead database, warmup and the Deliverability Hub. lemlist also lists inbox rotation, rotating IPs and in-app domain and email purchase among its deliverability features, which makes it workable for volume, though it costs more than Instantly or Smartlead at the entry tier. The Multichannel plan adds LinkedIn visits, invites, messages, voice notes and InMail, SMS, a power dialer and a WhatsApp add-on, with five senders per user. Lead enrichment and intent signals are separate add-ons. The 14-day trial gives Multichannel features without calling, plus 200 credits, which is enough to judge whether the personalization depth justifies the price for your campaigns.
Standout feature
The Email plan includes unlimited users and senders with 50,000 emails a month at $55 billed yearly.
Use cases
Founders
Send image-personalized cold emails to a short list of target accounts
Outcome: Messages that stand out in the inbox
Outbound teams
Add LinkedIn invites and voice notes after two email steps
Outcome: A second channel for non-responders
SDR teams
Use AI agents to research accounts before writing first lines
Outcome: Less manual research per prospect
Key features
- Email plan with unlimited users and email senders and 50,000 emails a month
- 650M+ lead database with email and phone finder
- lemAgent AI agents for signals, enrichment and messaging
- Warmup, inbox rotation and a Deliverability Hub
- LinkedIn, SMS, WhatsApp add-on and a power dialer on Multichannel
Pros
- Unlimited users and senders on the Email plan
- Deep personalization with Liquid syntax, custom text and images
- 14-day trial covers Multichannel features except in-app calls
Cons
- Lead enrichment credits are a $16 to $20 monthly add-on
- LinkedIn and calling steps require the pricier Multichannel plan
- Higher entry price than most volume-focused senders
Rank 5
Snov.io
A sales suite that combines an email finder, verifier, warmup, multichannel campaigns and a CRM, priced by credits and recipients.
snov.io8.4
out of 10
Best for: Small teams that want to find, verify and email prospects in one account with unlimited seats.
Snov.io bundles the prospecting and sending sides of cold email under one subscription. Credits pay for prospect search, email finding and verification, while sending is metered by recipients: you pay once when you first contact a lead, and all follow-ups to that person in the same billing period are free. Starter includes 1,000 credits, 5,000 recipients and three simultaneous mailbox warmups, while Pro tiers move to 5,000 credits, 25,000 recipients and unlimited warmups. Campaigns support unlimited senders, mailbox rotation, A/B testing, spintax and controls for new recipient volume. Deliverability tools include a spam word checker, DNS and blacklist checks and placement tests. A sales CRM with HubSpot and Pipedrive two-way sync is included, and LinkedIn automation is a separate $69 slot. The warmup cap on Starter is the main limit for multi-inbox senders.
Standout feature
Recipients are billed once per period, so follow-ups to the same lead do not use extra quota.
Use cases
Founders
Find and verify emails, then send a sequence from the same account
Outcome: No separate data tool to pay for
Small sales teams
Share credits and do-not-email lists across unlimited seats
Outcome: Consistent outreach across reps
Agencies
Run deliverability and blacklist checks before launching a client campaign
Outcome: Problems caught before sending
Key features
- Unlimited senders, follow-ups and campaigns on every plan
- Billing by recipients, with follow-ups to the same recipient free in a billing period
- Email warmup, deliverability check, blacklist and DNS checkers
- 7-tier email verification and bulk prospect search
- Sales CRM with HubSpot and Pipedrive two-way sync
Pros
- Unlimited team seats on every plan
- Annual billing saves 25%
- MCP access lets external AI assistants work inside the account
Cons
- Starter warms only 3 mailboxes at once
- LinkedIn automation costs $69 per account slot a month
- Starter includes 5,000 recipients and 1,000 credits
Rank 6
Woodpecker
A cold email tool for one-to-one style campaigns with free verification, warmup, inbox rotation and an optional LinkedIn tier.
woodpecker.co8.3
out of 10
Best for: Agencies and small teams that want condition-based campaigns, free verification and unlimited team members.
Woodpecker focuses on cold email that reads like individual messages, with condition-based campaigns that branch on what a prospect does, adaptive sending and inbox rotation across unlimited connected accounts. Plans are sized by monthly sends, with tiers from 5,000 to 1,000,000 emails, and every plan includes unlimited team members and contact storage. Email verification through Bouncer is free and unlimited, which removes a common extra cost. Three warmups are included, so teams running many new inboxes will buy more as an add-on. The Multichannel plan adds a cloud-based LinkedIn account for messages, InMail, connection requests and profile visits within LinkedIn limits. Integrations cover HubSpot, Pipedrive, Calendly, Zapier, Clay, an API and an MCP server. The pricing page renders prices by currency in the browser, so check the USD figure there before buying.
Standout feature
Unlimited email verification is included in every plan instead of being billed as credits.
Use cases
Agencies
Manage several client accounts from the agency panel
Outcome: Client campaigns kept separate
Founders
Verify a scraped list for free before the first send
Outcome: Fewer bounces on new domains
Recruiters
Combine email and LinkedIn steps in one campaign
Outcome: Candidates reached on two channels
Key features
- Unlimited email accounts and unlimited team members
- Unlimited email verification through Bouncer
- Three warmups included, with more as an add-on
- Inbox rotation, adaptive sending and condition-based campaigns
- Multichannel plan with LinkedIn messages, InMail, invites and profile visits
Pros
- 14-day trial with all features and no credit card
- Verification is included rather than sold as credits
- Agency panel available as an add-on
Cons
- Only three warmups come with each plan
- The pricing page shows prices in a selected currency, so we could not confirm USD from here
- Lead Finder starts at 100 credits
Rank 7
Apollo.io
A sales platform that pairs a large B2B contact database with email sequences, a dialer and a deliverability suite.
apollo.io8.2
out of 10
Best for: Founders who want to build lists and start cold email on a free plan before buying a dedicated sender.
Apollo is a prospecting database first and a sender second, which is both its strength and its limit for this list. Email campaigns are included on every account, including the free plan, so a founder can build a list and send a first sequence without paying. The free plan only connects Gmail accounts; paid plans add Microsoft and other providers. Sequences mix email, call and networking steps, AI drafts copy from contact and account data, and a built-in deliverability suite watches the email side. Basic covers email sequencing and core integrations, Professional adds higher credit limits and call recording, and every seat on an account must share one plan. For teams sending tens of thousands of emails across dozens of new domains, a dedicated sender with unlimited mailboxes will fit better, but Apollo is a strong place to find contacts and test messaging first.
Standout feature
Email campaigns are included on every Apollo account, even the free one.
Use cases
Founders
Pull a target list and send a first sequence from Gmail on the free plan
Outcome: Messaging tested before any spend
SDR teams
Combine email steps with parallel dialing
Outcome: Calls and emails tracked together
Outbound teams
Export verified contacts to a dedicated sending tool
Outcome: Data from Apollo, volume elsewhere
Key features
- Email campaigns included on every account, including free
- Multichannel sequence steps across email, calls and networking platforms
- Built-in deliverability suite for sequence email
- AI drafting from contact and account data
- Parallel and power dialers with CRM logging
Pros
- Free plan with no time limit
- Prospect data and sequences live in one system
- Apollo says over 600,000 companies use it
Cons
- Free plans can connect Gmail accounts only
- All seats on an account must be on the same plan
- Not built around rotating volume across many inboxes
Rank 8
QuickMail
A cold email and LinkedIn outreach platform that sends through your own providers' servers, with Inbox Rotation and free warmup through MailFlow.
quickmail.com8.1
out of 10
Best for: Agencies and small teams that want unlimited senders and users at a flat monthly price.
QuickMail keeps pricing simple: three flat plans, each with unlimited email senders, LinkedIn accounts and users. Starter covers 1,000 uploaded contacts and 5,000 emails a month, Growth 25,000 contacts and 100,000 emails with API access, and Agency 100,000 contacts and 500,000 emails with two workspaces and webhooks. Inbox Rotation spreads sends across connected inboxes, and warmup through MailFlow is included at no charge. QuickMail does not use its own sending servers; it automates sending through each inbox's provider, so Gmail mail goes out over Google's infrastructure. The 14-day trial requires a card but QuickMail says it does not convert into a paid subscription automatically. The feature set is narrower than Instantly or Smartlead, with no built-in lead database, but the flat model is easy to budget for agencies adding clients and teammates.
Standout feature
Every plan includes unlimited senders, LinkedIn accounts and users at a flat price.
Use cases
Agencies
Run client campaigns in separate workspaces on the Agency plan
Outcome: Clients kept apart under one bill
Outbound teams
Rotate a campaign across many connected inboxes
Outcome: Volume spread across senders
Founders
Add teammates without buying seats
Outcome: Whole team in the tool at no extra cost
Key features
- Unlimited email senders, LinkedIn accounts and users on every plan
- Inbox Rotation across connected senders
- Free AutoWarmer with MailFlow
- 5,000 emails a month on Starter, 100,000 on Growth and 500,000 on Agency
- API on Growth and webhooks on Agency
Pros
- No per-seat charges
- Trial ends without an automatic subscription
- Sends through each inbox's own provider, such as Google or Microsoft
Cons
- A card is required to start the trial
- Starter holds 1,000 uploaded contacts
- API access starts on Growth
Rank 9
Mailshake
A cold email tool with simple sequences, AI copywriting and a phone dialer on its top plan.
mailshake.com7.8
out of 10
Best for: Solo founders and small teams starting cold email from one or two addresses who want an easy setup.
Mailshake is the easiest entry point on this list but the weakest fit for many-inbox volume. Starter covers one email address and 1,500 sends a month, with unlimited contacts, warmup, verification and campaigns, plus A/B testing and SHAKESpeare AI copy. Email Outreach raises that to two addresses with unlimited sends and adds email rotation, advanced scheduling and throttling, a unified inbox and Salesforce, Pipedrive and HubSpot integrations. Sales Engagement gives 10 addresses, a power dialer with five phone numbers and free minutes to North American numbers, and 2,500 data finder credits. Anyone needing more addresses goes to the quote-based Agency plan. Data Finder and ready-made mailboxes are add-ons. Because addresses are counted per plan, Mailshake gets expensive for teams running dozens of inboxes, but for a founder starting with one domain it is simple and cheap.
Standout feature
Starter costs $25 a month billed yearly and still includes unlimited warmup and verification.
Use cases
Solo founders
Send a first sequence from one address with AI-written copy
Outcome: Outbound running in an afternoon
Small sales teams
Mix email steps with power dialing on Sales Engagement
Outcome: Calls and emails in one place
Consultants
A/B test subject lines on a small list
Outcome: Clearer read on what gets replies
Key features
- Automated email sequences with A/B testing
- SHAKESpeare AI email writing
- Unlimited warmup and email verification
- Email rotation, unified inbox and CRM integrations on Email Outreach
- Power dialer with free minutes to North American numbers on Sales Engagement
Pros
- Lowest entry price we found at $25 a month billed yearly
- Unlimited uploaded contacts and campaigns
- Simple plan structure
Cons
- Starter allows 1 email address and 1,500 sends a month
- Email rotation starts on Email Outreach
- Only 10 addresses on Sales Engagement, so many-inbox setups need the Agency plan
Frequently asked questions
+What is the best cold email software in 2026?
Instantly is our top pick for teams sending across many inboxes because every Outreach plan includes unlimited email accounts and warmup, starting at $37.60 a month billed yearly. Smartlead is the closest alternative and adds white-label workspaces for agencies.
+Which cold email tools allow unlimited email accounts?
Instantly, Smartlead, Saleshandy, QuickMail and Woodpecker all connect unlimited email accounts without per-inbox fees, and lemlist's Email plan lists unlimited users and email senders. Snov.io allows unlimited senders but warms only three mailboxes at once on Starter.
+What is the cheapest cold email software?
Mailshake Starter costs $25 a month billed yearly but covers one email address and 1,500 sends. Snov.io Starter costs $29.25 a month billed yearly, Smartlead Base $32 and Saleshandy Starter $34. Apollo.io has a free plan with email campaigns from Gmail accounts.
+Is Instantly or Smartlead better?
Both connect unlimited mailboxes. Instantly scored higher on ease of use and has clearer plan limits, while Smartlead suits agencies that want white-label client workspaces, in-app mailbox buying and dedicated-IP servers as add-ons.
+Do I need separate warmup software?
Usually not. Instantly, Smartlead, Saleshandy, lemlist, Mailshake, Snov.io, Woodpecker and QuickMail include warmup, though Snov.io Starter and Woodpecker cap how many mailboxes you warm at once without an add-on.
