Email & Sending

Deliverability & sender reputation

Practical steps to keep your funnels landing in the inbox — authentication, warm-up, list hygiene, and monitoring.

Last updated July 2, 2026

Deliverability in one sentence

Deliverability is the odds your mail reaches the inbox instead of spam — and it is earned through authentication, consistent sending, clean lists, and engaged recipients.

Authenticate everything

Before volume matters, get the basics right:

  • SPF, DKIM, and DMARC on your sending domain. Unauthenticated mail is filtered aggressively.
  • A dedicated sending domain or subdomain so your funnel reputation is not tangled with unrelated mail.

Warm up new domains and IPs

A brand-new domain has no reputation. Ramp volume gradually over two to four weeks, starting with your most engaged contacts, so mailbox providers learn to trust you. Sudden spikes from a cold domain are the fastest way into the spam folder.

Keep your list clean

  • Import validated addresses — the contact importer flags invalid, disposable, and risky emails.
  • Remove hard bounces immediately and suppress repeat non-openers.
  • Honor unsubscribes instantly; every funnel email includes an unsubscribe path.

Send to people who want it

Engagement is the strongest signal. Target segments of active contacts rather than blasting your whole list. Higher opens and clicks lift placement for everyone on your domain.

Monitor reputation

The platform tracks bounces, complaints, and reputation signals for your account so problems surface early. If a metric drifts, pause, investigate the recent send, and clean before resuming.

Quick checklist

  • SPF, DKIM, DMARC verified
  • Dedicated sending domain
  • Gradual warm-up for new domains
  • Validated, deduplicated list
  • Segmenting to engaged contacts
  • Bounces and complaints monitored
