Verify + harvest
Sales Development & Outbound

Four sendrules capabilities mapped to the pain that defines this segment. Every one of them is on the free plan.

  • Per-recipient quality gate
  • Autoresponder harvest
  • Sender affinity
  • Inbox placement testing
The pain

What you deal with today.

Cold outbound depends on two things you cannot see: whether the address is real, and whether the reply is useful. Your sequencing tool ignores autoresponders — but the OOO reply from your target frequently names their delegate, the person actually covering the desk this week, the referral you would otherwise never reach.

How sendrules answers

What changes when you route through us.

sendrules pipes your sequencing tool through an inline quality gate (Reacher-backed SMTP verification, syntax, disposable, role) so bad addresses never leave. On the return path, the autoresponder parser reads every OOO reply and writes the delegate's email into a contact list — webhook or CSV — that you can drop straight back into your next campaign.

The four capabilities

Feature per pain, not the other way round.

Per-recipient quality gate

Six checks in the SMTP DATA phase — syntax, suppression, disposable, role, typo, Reacher SMTP verify. Reject or quarantine per rule. You never send to a burnt address.

Autoresponder harvest

Rule-based extractor reads every OOO reply, captures the delegate email + any regex fields (name, phone, escalation contact), writes to a named contact list.

Read more →

Sender affinity

Sticky map remembers which sender first talked to a recipient. Follow-ups from the same rule always go through the same sender — protects your reply-rate signal.

Inbox placement testing

Seed-list monitoring tells you which mail is landing in Primary vs Promotions vs Spam per ISP, per sequence, per week.

Where it lands

Concrete scenarios you can wire in this week.

  • Cold outreach with the quality gate stopping typo'd or role-based addresses before your ESP sees them
  • Autoresponder parser building a 'covering colleague' list from every OOO reply, delivered by webhook into your sequencer
  • Sender affinity so a prospect's reply always comes back to the same sender across a 5-touch sequence
  • DMARC + auth-check on your outbound domains so a bad wave doesn't quietly drop your inbox rate
  • Per-sequence share-link reports for RevOps to review deliverability alongside reply-rate
