Everything you need to run outreach

From a single blast to a multi-step drip — all from a mailbox your recipients already trust.

Merge tags that just work

Drop {{FirstName}} or {{Company}} anywhere in your subject or body. Fields auto-detect from your CSV and render per recipient before each send.

Sent from your real Gmail

No ESP, no shared IPs. Mail goes through your own mailbox over the official Gmail API, so SPF, DKIM and DMARC are handled by Google.

Opens, clicks & replies

A tracking pixel and link redirector capture engagement, while a background worker watches your threads for replies and bounces.

Throttled to daily caps

Sending automatically respects Gmail's per-account limits with a rolling 24-hour window — connect more mailboxes to send more.

Drip sequences

Chain timed follow-ups with per-step delays. Enroll recipients and let the sequencer fire each step on schedule.

Reusable templates

Save your best-performing emails as templates and reuse them across campaigns and sequences.
