Step by step in Cloudflare

Verify your domain

Your email provider needs proof that you control this domain before it accepts email for it.

Type
TXT
Name
@
Content
Copy it from Migadu admin (see below)

Where to find your value

Copy the verification record shown for your domain in the Migadu admin (admin.migadu.com).

We haven’t been able to confirm this value from Migadu's public docs yet, so we don’t show one.

In Cloudflare

  1. On the DNS Records page, select Add record.
  2. Choose TXT as the Type.
  3. Fill in Name and Content.
  4. Select Save.

Point your MX records

MX records tell other mail servers where to deliver your email. How MX works

Type
MX
Name
@
Priority
10
Mail server
aspmx1.migadu.com
Type
MX
Name
@
Priority
20
Mail server
aspmx2.migadu.com

In Cloudflare

  1. On the DNS Records page, select Add record.
  2. Choose MX as the Type.
  3. Fill in Name, Mail server and Priority.
  4. Select Save.
  5. Delete any other MX records: select Edit on each one, then Delete, and confirm.
  6. Repeat for each MX record above.

Add the SPF record

SPF lists the services allowed to send email as you. How SPF works

Type
TXT
Name
@
Content
v=spf1 include:spf.migadu.com -all
  • A domain must have only one SPF record. If you already have one, add include:spf.migadu.com to it instead of creating a second.

In Cloudflare

  1. On the DNS Records page, select Add record.
  2. Choose TXT as the Type.
  3. Fill in Name and Content.
  4. Select Save.

Set up DKIM

DKIM signs your mail so receivers can trust it. How DKIM works

Type
CNAME
Name
key1._domainkey
Target
key1.yourdomain.com._domainkey.migadu.com
  • The target includes your own domain name, so each domain's DKIM target is different.
  • Migadu's example ends the target with a period. Add it only if your DNS host asks for fully qualified names.
Type
CNAME
Name
key2._domainkey
Target
key2.yourdomain.com._domainkey.migadu.com
Type
CNAME
Name
key3._domainkey
Target
key3.yourdomain.com._domainkey.migadu.com

In Cloudflare

  1. On the DNS Records page, select Add record.
  2. Choose CNAME as the Type.
  3. Fill in Name and Target.
  4. Set Proxy status to DNS only (grey cloud).
  5. Select Save.
  6. Repeat for each CNAME record above.

Add the DMARC record (recommended)

DMARC tells receivers what to do with mail that fakes your domain. How DMARC works

Type
TXT
Name
_dmarc
Content
v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com
  • Start with p=none (no action) and read the reports for a while. Replace the report address with a mailbox you actually read.
  • Migadu suggests v=DMARC1; p=quarantine; which asks receivers to treat failing mail as suspicious (usually spam). Move to it once SPF and DKIM pass.

In Cloudflare

  1. On the DNS Records page, select Add record.
  2. Choose TXT as the Type.
  3. Fill in Name and Content.
  4. Select Save.

Check your setup

Once the records are saved, run a live check. We look up your domain in public DNS and tell you what is right, missing or wrong, with the fix in Cloudflare’s words.

We only read public DNS records. Nothing is stored.

Common mistakes with Migadu on Cloudflare

Using a DKIM target without your domain

Each DKIM CNAME points to a target that contains your own domain, like key1.yourdomain.com._domainkey.migadu.com. Copy the full target for your domain.

Adding only one DKIM record

Migadu uses three DKIM CNAME records: key1, key2 and key3. Add all three.

Cloudflare: Keep email CNAMEs on DNS only

Set Proxy status to DNS only (grey cloud) for DKIM and verification CNAME records. Cloudflare says records used for email or domain verification should not be proxied, and may block proxying DKIM CNAMEs.

Cloudflare: Turn off Cloudflare Email Routing first

If Email Routing is on, Cloudflare has added locked MX records (route1, route2 and route3.mx.cloudflare.net) and an SPF record with include:_spf.mx.cloudflare.net. Unlock them or disable Email Routing (Compute > Email Service > Email Routing > your domain > Settings) before switching to another provider. Email Routing can't be used with an outside mail server.

Migadu on Cloudflare: questions

Where do I add Migadu DNS records in Cloudflare?

Sign in to the Cloudflare dashboard and select your domain. Open the DNS Records page. Add each record there, one at a time.

What goes in the Name field at Cloudflare?

Enter @ for records on your bare domain, such as MX and SPF. For the others, enter only the part before your domain, for example key1._domainkey. Cloudflare adds your domain automatically.

Do I need to delete my existing MX records at Cloudflare?

Yes. Sending servers pick an MX record by its priority (lowest number first) and fall back to the others, so a leftover MX record can receive some or all of your mail. Keep only the Migadu MX records and delete the rest. If Email Routing is on, Cloudflare has added locked MX records (route1, route2 and route3.mx.cloudflare.net) and an SPF record with include:_spf.mx.cloudflare.net. Unlock them or disable Email Routing (Compute > Email Service > Email Routing > your domain > Settings) before switching to another provider. Email Routing can't be used with an outside mail server.

Where do I get my Migadu DKIM record?

Migadu DKIM records are CNAME records whose value includes your domain, for example key1.yourdomain.com._domainkey.migadu.com. Copy the exact values for your domain from the table on this page.

How long until Migadu email works on Cloudflare?

Cloudflare says changes to your DNS records take effect worldwide within 5 minutes, usually much less. A record you replaced can stay cached until its old TTL runs out.
