Step by step in Bluehost

Verify your domain

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

Type
TXT
Host Name
@
TXT Value
Copy it from Proton Mail settings (Domain names) (see below)

  2. Set Record Type to TXT and Refers to to Other Host.
  3. Enter the Host Name and paste the TXT Value.
  4. Click Add.

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 Record
@
Priority

  • Delete any other MX records, or make sure Proton's have the lowest priority number.

  3. Save the record.
  4. 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
@
TXT Value
v=spf1 include:_spf.protonmail.ch ~all
  • Keep one SPF record. To keep an existing one, add include:_spf.protonmail.ch right after v=spf1.

  2. Set Record Type to TXT and Refers to to Other Host.
  3. Enter the Host Name and paste the TXT Value.

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 Record
protonmail._domainkey
Points to
Copy it from Proton Mail settings (Domain names) (see below)

Where to find your value

Copy the exact target from the DKIM tab of your domain in Proton Mail settings.

  • Add all three DKIM records; Proton rotates keys between them.
  • Some hosts reject a trailing period on CNAME values. If yours does, remove the final dot.
Type
CNAME
Host Record

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
TXT Value
v=DMARC1; p=quarantine
  • Proton recommends a p=quarantine policy for most domains.

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 Bluehost’s words.

We only read public DNS records. Nothing is stored.

Common mistakes with Proton Mail on Bluehost

Adding only one DKIM record

Proton uses three DKIM CNAMEs (protonmail, protonmail2, protonmail3). Add all three, matching the values in your setup wizard exactly.

Bluehost: Replace Bluehost's default MX record

By default Bluehost's MX record points to your own domain, which delivers mail to Bluehost's local server. Change it to your provider's mail server.
