MailerLite
MailerLite is a budget-friendly marketing platform. Authentication uses SPF include and DKIM TXT on a sending subdomain.
DNS records to publish
| Type | Host | Value |
|---|---|---|
| TXT | @ | v=spf1 include:_spf.mlsend.com ~allSPF |
| TXT | ml._domainkey | k=rsa; p=<public key>DKIM |
Authentication setup
SPF
Add include:_spf.mlsend.com to SPF.
DKIM
Publish the TXT record MailerLite generates.
DMARC
Standard rollout.
Deliverability tips
- Clean inactive subscribers every quarter — MailerLite's lower-tier plans don't suppress unengaged contacts automatically.
- Use the segmentation rules to avoid sending the same broadcast to recently emailed contacts.
- Verify both DKIM and SPF; MailerLite's setup wizard sometimes skips one of them.
