DNS & Technical Setup

The technical deliverability checklist

Wording is only 20% of deliverability. Ensure your sending infrastructure is verified:

SPF Record (Authorized Sender)

Declares which IP addresses are permitted to send mail for your domain.

DKIM Key (Cryptographic Seal)

Digitally signs each message to prove it wasn't forged or modified.

DMARC Policy (Protection)

Enforces how receiving servers handle SPF/DKIM verification failures.

Custom Tracking Domain

Replaces third-party tracking links with your own dedicated subdomain.

Mailbox Warmup (14+ Days)

Builds positive reply signals with peers before starting cold campaigns.

Volume Caps (<35 emails/day)

Keep daily outbound volume under 35 messages per inbox to avoid throttling.
