Email automation covers three jobs, and Emailchaser does all three in one account.
Campaigns send the opening email and schedule every follow-up from your own mailboxes, and a follow-up stops when the lead replies.
Warm-up and inbox rotation spread the volume across your mailboxes so each one keeps a healthy sending record.
The Unibox collects every reply in one list, and on Max and Enterprise interested leads move into the Sales CRM pipeline.
Autopilot sets the campaign up from your website and waits for one approval.
You can automate a campaign from your own mailboxes in five steps.
- ConnectAdd your Google, Outlook or SMTP mailboxes, as many as you like.
- Warm upLet warm-up ramp each mailbox up gradually before it sends at full volume.
- Add leadsFind prospects in the Lead Finder and verify them before you send.
- WriteDraft an opening email and its follow-ups, or let Autopilot write the 4-email sequence.
- LaunchStart the campaign and answer replies from the Unibox.
Every sequence shows its status and progress in one list.
Campaign analytics count replies, positive replies, bounces and emails sent.
We compared the tools on five things that decide how well email automation works.
- The emails a month the cheapest paid plan sends.
- Whether mailboxes are unlimited or counted in the plan.
- Whether warm-up, verification and a lead source come in the plan.
- How follow-ups and A/B tests are set up.
- The monthly price, read from the vendor's own pricing page.

SEE REVIEWSP.s. these are actually real reviews (not fake G2 reviews) 🙂
“Btw thanks for your continuous help, best support ever! It means a lot as when I understand how the tool works, esp. In problematic situations, and And what it can do and cannot so from the start, I have more trust. There’s nothing worse for a user than what Smartlead does: lots of great features that don’t really work, including crucial ones for a sequencer like auto fallback to connected accounts when account gets disconnected (doesn’t have to get back to the original one after reconnection, no one expects miracles, just a solid infra delivering on its specs - not promises), plus their low quality support when the issues are revealed.”
“Got my first reply with Emailchaser :)”
“We've recently upgraded to the premium plan to increase our sending volume. Just wanted to say thanks for such an awesome platform and the support you've already given in getting us started.”
