Before you start
- Have your Migadu account ready. Some values are unique to your account and come from the Migadu admin.
- Open DNS at IONOS: Sign in at login.ionos.com, select Menu, then Domains and SSL. Under Actions for your domain, select the gear icon, then DNS.
- Keep both tabs open and add the records below one at a time.

Step by step in IONOS
Verify your domain
Your email provider needs proof that you control this domain before it accepts email for it.
- Type
- TXT
- Host name
- Leave this field empty
- Value
- 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 IONOS
- Select Add record, then the TXT section.
- Leave Host name empty for your bare domain, paste the Value, and choose a TTL.
- Select Save.
Point your MX records
MX records tell every other mail server where to deliver email for your domain. They must point to your provider and nowhere else.
- Type
- MX
- Host name
-
@ - Priority
- 10
- Points to
-
aspmx1.migadu.com
- Type
- MX
- Host name
-
@ - Priority
- 20
- Points to
-
aspmx2.migadu.com
In IONOS
- Select Add record, then the MX section.
- Enter @ as Host name, the mail server in Points to, and the Priority. Choose 1 hour for TTL.
- Select Save.
- If other MX records are listed, delete each one with the Delete record (trash can) icon.
- Repeat for each MX record above.
Add the SPF record
SPF is a TXT record that lists the services allowed to send email from your domain, so receivers can spot forgeries.
- Type
- TXT
- Host name
- Leave this field empty
- Value
-
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 IONOS
- Select Add record, then the TXT section.
- Leave Host name empty for your bare domain, paste the Value, and choose a TTL.
- Select Save.
Set up DKIM
DKIM publishes a public key so receivers can confirm your messages really came from you and were not changed on the way.
- Type
- CNAME
- Host name
-
key1._domainkey - Alias
-
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
- Host name
-
key2._domainkey - Alias
-
key2.yourdomain.com._domainkey.migadu.com
- Type
- CNAME
- Host name
-
key3._domainkey - Alias
-
key3.yourdomain.com._domainkey.migadu.com
In IONOS
- Select Subdomains, then Add subdomain, and enter the record's name (for example autodiscover).
- Under Actions for the new subdomain, select the gear icon, then DNS.
- Select Add record, then the CNAME section.
- Enter the target in the Alias box, tick the I am aware disclaimer if it appears, and select Save.
- Repeat for each CNAME record above.
Add the DMARC record (recommended)
DMARC tells receivers what to do with mail that fails SPF and DKIM, and where to send reports about it.
- Type
- TXT
- Host name
-
_dmarc - Value
-
v=DMARC1; p=quarantine;
- This is the value Migadu suggests. It asks receivers to treat failing mail as suspicious (usually spam), so make sure SPF and DKIM pass first.
In IONOS
- Select Add record, then the TXT section.
- Leave Host name empty for your bare domain, paste the Value, and choose a TTL.
- 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 IONOS’s words.
Common mistakes with Migadu on IONOS
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.
Adding a second SPF record
A domain must have only one SPF record. If you already have one, add include:spf.migadu.com to it.
IONOS: CNAME records go on their own subdomain
IONOS supports only one top-level CNAME record, so each CNAME is created by first adding a subdomain and then giving it an Alias.
IONOS: MX and a top-level Autodiscover CNAME can't coexist
IONOS doesn't allow a domain to have both an MX record and a top-level Autodiscover CNAME. Microsoft's guide uses the subdomain method above for Autodiscover.

Migadu on IONOS: questions
Where do I add Migadu DNS records in IONOS?
Sign in at login.ionos.com, select Menu, then Domains and SSL. Under Actions for your domain, select the gear icon, then DNS. Add each record there, one at a time.
What goes in the Host name field at IONOS?
Leave it empty 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. IONOS adds your domain automatically.
Do I need to delete my existing MX records at IONOS?
Yes. Mail servers deliver to every MX record you publish, so keep only the Migadu MX records and delete the rest.
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.
