# DKIM record for MailerLite

URL: https://iblockspam.com/dkim/mailerlite
Last updated: 2026-11-03

Record type: CNAME
Selectors: litesrv
Key managed by: Provider (CNAME delegation)

MailerLite signs your campaigns through a single CNAME record: the name `litesrv._domainkey` on your sending domain points to `litesrv._domainkey.mlsend.com`, where MailerLite publishes the key. You add it from **Account settings > Domains** together with an SPF TXT record and a verification TXT record, then run **Check DNS records** until the domain reads Authenticated.

## DNS records

- DKIM selector litesrv (CNAME, host litesrv._domainkey): `litesrv._domainkey.mlsend.com` Some hosts want a trailing period (`litesrv._domainkey.mlsend.com.`) so they don't append your domain to the target.
- SPF record (on the same host as any existing SPF record) (TXT, host @): `v=spf1 a mx include:_spf.mlsend.com ~all` MailerLite's example. Merge the include into an existing record instead of adding a second one.
- Domain verification (TXT, host @): `<verification value shown in MailerLite>`

## Set it up and turn on signing

- Go to **Account settings**, select the **Domains** tab and click **+ Add sending domain**. Enter the address you send from and click **Save**.
- If your DNS provider is a MailerLite partner, use the automatic option. Otherwise choose **Authenticate manually**.
- Create the CNAME with the name `litesrv._domainkey` only; MailerLite says adding your domain to the end of the name isn't necessary. At Cloudflare, set the record to DNS only.
- Add the SPF and verification TXT records, leaving TTL at the default.
- Back in MailerLite, open the **…** menu next to the domain and click **Check DNS records**.

## DMARC alignment

The `litesrv` key lets MailerLite put your domain in the DKIM signature, so the DKIM result matches the domain in your From address and DMARC can pass on it. MailerLite requires this authentication before you send from a custom domain once the 14-day trial ends. Its help articles don't describe a custom return path, so plan on DKIM as the aligned result.

## Key length and rotation

Because the name is a CNAME into `mlsend.com`, the public key stays in MailerLite's zone and MailerLite can replace it without asking you to edit DNS. The selector `litesrv` is the same for every account, which is why the record value never changes. MailerLite doesn't publish its key length or a rotation schedule in these articles.

## Common mistakes

- **A doubled name such as `litesrv._domainkey.example.com.example.com`.** Enter only `litesrv._domainkey` when your host adds the domain.
- **The target rewritten to `litesrv._domainkey.mlsend.com.example.com`.** End the value with a period if your host appends the zone.
- **A proxied record at Cloudflare.** MailerLite asks for proxy status off (DNS only).
- **Records in a zone that isn't live.** Check that your nameservers point to the provider where you edited DNS.

**Q: What is MailerLite's DKIM selector?**
`litesrv`. The record is a CNAME named `litesrv._domainkey` on your sending domain, pointing to `litesrv._domainkey.mlsend.com`. Check it with our DKIM Checker using the selector `litesrv`.

**Q: How long does MailerLite take to verify DKIM?**
MailerLite says approval often takes minutes, propagation is usually complete within 24 hours, and it can take up to 72. Click Check DNS records again once the CNAME resolves.

**Q: Why does MailerLite say my CNAME value is wrong?**
Many DNS hosts silently append your domain to the target. MailerLite's fix is to enter the value with a trailing period, `litesrv._domainkey.mlsend.com.`, so the host stores it exactly.
