Publish SPF record

Add a TXT DNS record listing authorized sending hosts and include mechanisms for services.

Include all sending services in SPF

Add include: entries for ESPs, marketing platforms, and third-party senders.

Consolidate to a single SPF record

Combine mechanisms and avoid multiple SPF TXT records for the same domain.

Generate DKIM key pair

Create 1024- or 2048-bit keys and store your private key securely.

Publish DKIM DNS TXT record

Add the public key as selector._domainkey TXT for each selector used.

Enable DKIM signing in the sending service

Turn on signing and verify the selector and alignment in test messages.

Create a DMARC record at p=none

Publish _dmarc TXT with rua/ruf reporting to collect alignment data first.

Monitor DMARC reports daily

Use a report parser to identify SPF/DKIM failures and unauthorized sources.

Move DMARC to p=quarantine after 7–14 days

Switch policy only if failures are low and authorized senders are verified.

Shift DMARC to p=reject after continued monitoring

Enforce reject for unauthenticated mail once data shows stable alignment.

Publish BIMI record with verified logo

Add BIMI TXT pointing to a hosted SVG logo; consider a VMC for wider support.

Plan dedicated sending IP warmup schedule

Map daily volume increases over 2–4 weeks with clear targets and thresholds.

Warm up dedicated sending IP per schedule

Start with low volume, monitor metrics, and increase volumes gradually each day.

Implement bounce and complaint handling

Process bounces immediately, suppress hard bounces, and route complaints to suppression lists.

Monitor bounce and complaint rates weekly

Track rates and investigate spikes; aim to keep complaints and hard bounces minimal.

Perform list hygiene and unsubscribe handling

Remove inactive addresses, honor opt-outs promptly, and suppress repeated bounces.

Run inbox placement and spam tests with seed lists

Use testing tools to check placement across major ISPs before large sends.
