# SPF record for Mailjet

Last updated: 2026-10-22

Include: include:spf.mailjet.com
Where it goes: Your sending domain (@)
DNS lookups: 1 of 10

Mailjet's SPF value is v=spf1 include:spf.mailjet.com ~all, a TXT record on your domain (host @, or blank). If the domain already has an SPF record, Mailjet says to add include:spf.mailjet.com to it instead of creating a second record, for example v=spf1 include:spf.example1.com include:spf.mailjet.com ~all. The include costs 1 DNS lookup.

## Example records

- Mailjet only (Mailjet's value) (TXT, host @): `v=spf1 include:spf.mailjet.com ~all`
- Mailjet and Microsoft 365 (TXT, host @): `v=spf1 include:spf.protection.outlook.com include:spf.mailjet.com ~all`
- Mailjet and Google Workspace (TXT, host @): `v=spf1 include:_spf.google.com include:spf.mailjet.com ~all`

## Notes

- Mailjet explains the qualifiers but leaves the choice to you: `~all` marks unlisted servers as suspicious, `-all` rejects them and `?all` is neutral. Its own value uses `~all`.
- Mailjet reminds you that SPF is published as a TXT record; the old SPF record type isn't recommended.

## How to add it

- In Mailjet, add and validate your sending domain (Account Settings, Domains and Sender addresses). Mailjet then shows the SPF and DKIM values for it.
- Sign in to your DNS host and look for a TXT record on `@` that starts with `v=spf1`.
- If there is one, add `include:spf.mailjet.com` to it. If there isn't, create a TXT record with `v=spf1 include:spf.mailjet.com ~all`.
- Add the DKIM TXT record at `mailjet._domainkey` as well, using the key from your account.
- Check the result in Mailjet: Mailjet says an authenticated domain shows a green check mark next to SPF and DKIM. DNS can take from a few minutes to 48 hours.

## DKIM and DMARC

Mailjet's DKIM key is a TXT record at `mailjet._domainkey`, with a key Mailjet generates (2048 bits by default). See our [Mailjet DKIM page](https://iblockspam.com/dkim/mailjet). Mailjet also recommends a DMARC record, while noting its support only gives guidelines for DMARC rather than doing the setup for you.

## Common mistakes

- Keeping two `v=spf1` records, one for Mailjet and one for your mailbox provider. Mailjet's own example merges them into a single line.
- Choosing the obsolete SPF record type in your DNS host instead of TXT.

**Q: What is Mailjet's SPF include?**
`include:spf.mailjet.com`. On its own the record is `v=spf1 include:spf.mailjet.com ~all`; with another provider it becomes, for example, `v=spf1 include:spf.protection.outlook.com include:spf.mailjet.com ~all`.

**Q: How do I merge Mailjet into an existing SPF record?**
Keep one TXT record that starts with `v=spf1`, add `include:spf.mailjet.com` next to the includes already there, and keep a single `all` at the end. Delete the separate Mailjet record if you created one.

**Q: Where does Mailjet show whether SPF passes?**
Mailjet says to open Account Settings, Domains & DNS and select the domain: a green check mark next to SPF and DKIM means it's authenticated. Our [SPF Checker](https://iblockspam.com/tools/spf-checker) shows the live record and its lookup count.
