Built to protect your sender reputation
Your reputation is the most valuable thing you send from. Daily limits, warm-up, spacing, address checks, a tracking domain and automatic pauses keep it safe. No software can guarantee inbox placement; these are the settings that give you the best chance.
Limits and warm-up
A daily limit per mailbox, raised gradually on a new account, with emails spaced out.
Health checks
A mailbox that can't sign in, hits its provider's limit or bounces a lot is skipped, and you're told why.
Automatic pause
If too many emails bounce or are marked as spam, sending stops before damage is done.
What's included
Email checking
Built-in checks, or ZeroBounce and NeverBounce with your own key; results kept for 30 days.

Guides for this feature
Deliverability: common questions
Can you guarantee the inbox?
No one honestly can. We give you the settings that protect your reputation; relevant emails to the right people do the rest.
Do I need my own domain?
For one-to-one emails from Gmail or Outlook, no. For campaigns, yes: Gmail and Yahoo require SPF, DKIM and DMARC from bulk senders.
