A big send stays out of spam when the list is clean, the volume is spread out and the guards are on.

Clean the list

Verify every address before the first send, so a big list does not bounce.

Spread the volume

Unlimited mailboxes with warm-up and inbox rotation share the load, so no single mailbox sends too much.

Turn the guards on

Campaign settings skip duplicates, invalid addresses, past bounces and leads who already replied.

The free list cleaner removes duplicates and bad addresses and flags role and free-provider addresses.

Campaign settings keep a big send clean before the first email goes out.

  • Duplicate leads are removed automatically.
  • Leads with invalid emails are skipped, and you choose whether to contact catch-all addresses that were validated.
  • On Max and Enterprise, leads who already replied and sit in your Sales CRM are skipped.
  • Leads that exist in another campaign can be skipped, so nobody gets two sequences.
  • Personal addresses such as @gmail.com can be excluded.
  • Leads that previously hard bounced are skipped, including bounces seen by other Emailchaser users.

These are the sending options in the campaign settings, and the schedule can be set to a full day, a morning or an afternoon window.

  • Whether the plan sends from your own mailboxes or from the vendor's servers.
  • Whether the list is verified before it is sent.
  • Whether warm-up and inbox rotation come in the plan.

SEE REVIEWS

P.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.”
