Warmup is the boring part of Smartlead that decides whether the fun part works. Here is how to run it properly and when to graduate to real sending.

Direct answer: Smartlead warmup sends and receives low-volume emails between your mailboxes and a partner network to build sender reputation. Start at 20-30 emails per mailbox per day, ramp over 2-4 weeks, and only send real campaigns once a mailbox consistently shows 95%+ inbox placement.

Why does a new domain get blocked?

Because it has no history. Mailbox providers treat an unknown sender with suspicion, and a sudden burst of identical emails looks exactly like a spammer. Warmup manufactures the missing history: regular, varied, replied-to email traffic that looks like a normal human inbox gradually waking up.

How do you configure warmup correctly?

  1. Connect at least 3-5 mailboxes. Warmup needs volume between accounts; one lonely mailbox has nobody to talk to.
  2. Set daily volume. Begin at 20 emails per mailbox per day. Move up roughly 5 per day if reputation holds.
  3. Enable auto-replies. Warmup works because messages get replies and marked as important. Leave that on — it is the signal providers read.
  4. Watch the inbox rate. Smartlead reports delivery and inbox-vs-spam. Ignore vanity metrics; inbox percentage is the one that matters.
  5. Ramp slowly. Two to four weeks is realistic. Two days is not warmup, it is a countdown to spam folder.

What reputation signals should you trust?

Three numbers: inbox placement rate (want 95%+), spam rate (want under 2%), and reply rate during warmup (steady, not zero). If inbox rate sits below 90% after two weeks, something is wrong — usually DNS. Re-check SPF, DKIM, and DMARC before blaming the tool.

Does warmup guarantee inbox placement?

No. Warmup improves reputation, but copy and targeting still decide outcomes. A perfectly warmed mailbox sending an email that screams “bulk offer” still gets flagged. Warmup removes one obstacle; it does not remove all of them.

How long should you keep warmup running?

Common practice is to leave a low level of warmup running indefinitely to keep mailboxes active. Pure warmup for 2-4 weeks before launch, then a small trickle alongside real campaigns so the inbox never goes quiet. Sudden silence after heavy activity is itself a suspicious pattern.

Quick Summary

  • Warmup builds sender reputation by simulating normal inbox traffic.
  • Use 3-5+ mailboxes, start at 20-30 sends each per day, ramp over 2-4 weeks.
  • Target 95%+ inbox placement; below 90% after two weeks signals a DNS problem.
  • Warmup improves deliverability but cannot fix bad copy or targeting.
  • Keep a light warmup running even during live campaigns.

Getting the first campaign right is mostly about infrastructure, not copywriting.

Direct answer: To launch a Smartlead campaign, connect your sending accounts, run warmup for at least 14 days, create a campaign with your leads and sequence, then start sending slowly. Plans start around $39/month for the Basic tier, which includes 6,000 active leads and unlimited mailbox connections.

What is Smartlead used for?

It sends cold email to prospect lists from many mailboxes at once, so no single address hits spam limits. The built-in warmup feature sends and receives low volumes between your accounts and partner accounts to build sender reputation. That is the whole point — you cannot cold-email 2,000 people a day from one Gmail address and expect inbox placement.

How do you set up a campaign step by step?

  1. Buy the domains. Never send cold email from your main domain. Register a lookalike (e.g. yourbrand.co or yourbrand.io) and set SPF, DKIM, and DMARC before anything else.
  2. Connect mailboxes. In Smartlead, add sending accounts. Google Workspace and Microsoft 365 are supported, as are SMTP/IMAP providers.
  3. Start warmup immediately. Set each mailbox to 20-30 warmup emails per day and let it run two weeks before your real sends. Skipping this is the number-one reason campaigns land in spam.
  4. Import leads. Upload a CSV. Smartlead dedupes across campaigns so the same person is not emailed twice.
  5. Write the sequence. Two to four steps is plenty. Space them 3-4 days apart, no more than one follow-up per week.
  6. Rotate mailboxes. Enable rotation so sends spread across accounts, and cap each mailbox at 30-50 emails per day.

Is Smartlead free?

There is a 14-day free trial and a limited free tier, but real sending needs the Basic plan at roughly $39/month. Pricing scales with active lead count — the entry tier covers 6,000 active leads, and you pay more as that number grows. Mailbox connections are unlimited on paid plans, which matters because warmup wants volume.

What gets a campaign flagged as spam?

Volume spikes, a cold domain with no warmup history, and spammy copy. Smartlead cannot save you from all three. Its safeguards help with rotation and throttling, but if you connect a brand-new mailbox and blast 500 emails on day two, you will land in spam regardless of the tool.

Who is Smartlead for?

Agencies and B2B teams sending hundreds to thousands of cold emails per month. If you send 20 personalized emails a week, Smartlead is more infrastructure than you need — a plain inbox or a lighter tool would do. It rewards people who care about deliverability mechanics.

Quick Summary

  • Smartlead sends cold email via many rotating mailboxes with built-in warmup.
  • Warmup for at least 14 days before real sends; cap mailboxes at 30-50/day.
  • Basic plan starts near $39/month covering 6,000 active leads.
  • Always use secondary domains with SPF, DKIM, and DMARC configured.
  • Overkill for low-volume, highly personal outreach.
