List hygiene

Bad addresses never leave the queue.

Every recipient passes through a filter wall before sending. What comes out the other side is clean, deliverable, and safe for your domain.

  • Syntax & MX verification
    Malformed addresses and dead domains are dropped before they can bounce.
  • Suppression & unsubscribe lists
    Anyone who opted out is filtered from every future send, automatically.
  • Already-contacted skip
    People you've emailed before never get the same campaign twice.
  • Quota guards
    Sends stay inside Gmail's published limits — your reputation stays intact.

Sequences

Follow-ups that know when to stop.

Schedule up to five stages. The moment someone replies, everything after it cancels — automatically.

Day 0

Initial email

Personalized with merge tags, sent from your own address.

Day 3

Follow-up 1

“Just bumping this” — same thread, only to people who haven't replied.

Replied! — sequence stopped
Day 7

Follow-up 2

Skipped — the sequence already stopped itself.

Day 14

Break-up email

Skipped — no robot nudges after a human said yes.

Analytics

Know exactly what landed.

Opens, clicks, and replies attributed per recipient — with Gmail's machine prefetches filtered out, so the numbers describe humans.

FAQ

Questions, answered.

Does this send from my own Gmail address?

Yes — every message goes out through Google's own API from your account, lands in your Sent folder, and threads like normal mail. SendHustle never relays your mail through shared servers, which is exactly why it outperforms blast tools on deliverability.

Will Google flag my account?

SendHustle enforces the guardrails for you: daily caps per inbox, human-speed pacing between sends, send windows, and bounce monitoring that warns you before a bad list does damage. You stay inside Gmail's published limits.

How does reply detection actually work?

We watch the sending inbox for new thread activity and confirm each candidate before marking it. The moment a reply is confirmed, that person's follow-up sequence stops and any reply-trigger you configured fires — in the same thread.

What permissions do you take, and what do you store?

Google's consent screen lists every scope — sending mail, and reading the threads your campaigns created so replies can be detected. Refresh tokens are encrypted at rest (AES-256-GCM with key rotation), and you can revoke access from your Google account at any time.

Can my team send from multiple inboxes?

MultiSend lets teammates link their Gmail with an explicit consent flow (IP and timestamp recorded). Sends rotate across linked inboxes, each keeping its own daily quota — 5 linked accounts means 5× the safe volume.

Do recipients see anything weird?

No. They get a normal, personal email from a real person — personalized subject and body, regular threading, and a clean unsubscribe link if you enable it. The tracking pixel and link wrapping are the same techniques every email platform uses.

Your next reply is one campaign away.
