Autocloz vs Smartlead

Smartlead is a popular cold-email tool — unlimited mailboxes, warmup and rotation.

Smartlead does email well, but calling, LinkedIn, SMS and WhatsApp live in other tools you stitch together. Autocloz runs all five channels — plus a free CRM — under one login, so a lead's whole journey lives in one timeline.

Frequently asked

Is Autocloz a Smartlead alternative?

Yes. Autocloz covers the same cold-email essentials (unlimited mailboxes on paid, warmup, rotation, deliverability monitoring) and adds calling, LinkedIn, SMS, WhatsApp and a free CRM in the same platform.

Can I keep my existing mailboxes?

Yes — connect any number of Google/Microsoft/SMTP mailboxes. The free plan includes 50; paid plans are unlimited.

Does Autocloz charge per seat?

No. Every Autocloz plan includes unlimited users. You scale per-channel daily limits, not seats.

What do I actually give up by moving from Smartlead?

Smartlead is a mature, focused cold-email sender, and if email is your only channel it does that job well. Moving to Autocloz means trading a specialist for a platform: you keep unlimited mailboxes, warmup, rotation and deliverability monitoring, and you gain calling, LinkedIn, SMS, WhatsApp and a CRM in the same login. If you have built deep workflows around Smartlead-specific integrations, budget time to rebuild them.

How does the AI pricing differ?

Smartlead meters AI as add-on credits. Autocloz is bring-your-own-key: you connect your own OpenAI or Anthropic key and pay that provider directly at cost, with no per-credit markup from us. On high personalisation volume that is usually the larger of the two savings.

Can I run both while I migrate?

Yes, and it is the safer path. Point a subset of mailboxes at Autocloz, run a campaign side by side, and compare reply rates on the same list before you move the rest. Nothing about connecting a mailbox to Autocloz disconnects it from Smartlead.
