Setup a Custom Email Domain

These steps will ensure that Simplero is authorized to send email on your behalf. This will improve your site's email deliverability following the Gmail and Yahoo 2024 sender requirements

Start by navigating to Settings >> Email settings

  1. In the Sender domain section, click the blue + Add email domain button

  2. Add the domain part of the email you want to send as (e.g. if you're sending as, you would add the domain 

  3. You'll now see the TXT records and CNAME records that need to be added to your site's DNS - these records can take up to 24 hours to be verified. 

Although DNS providers differ on the way you add the records they fields you will find will be very similar to the ones described below.

The SPF record will be added on your DNS settings as Hostname= empty or @, Type=TXT, value=v=spf1

The DKIM record it will look like below: Hostname= value on the first column (, Type=TXT, value=SET value (k=rsa; t=s; p=MIGfMA0GCSqGS..)

Do the same with all the records (TXT and CNAME) provided to you on your Simplero dashboard.

   5. Once all have been added, click "Check Domain". 

*Note: You can only have one SPF record for each eamil domain. If you are using Simplero alongside with another email provider (fe:Simply), you'll need to combine the SPF record as below:

v=spf1 ~all

Adding DMARC

DMARC stands for “Domain-based Message Authentication, Reporting & Conformance.” DMARC is a protocol that uses Sender Policy Framework (SPF) and DomainKeys identified mail (DKIM) to determine the authenticity of an email message.

DMARC requires both SPF and DKIM to fail in order for it to act on a message. It is a required step in Gmail and Yahoo sender guidelines.

To setup DMARC for your email, follow these steps: 

Under Settings >> Sender Emails >> Sender Domains

1. Click + Add DMARC

2. Enter your email and hit "Setup DMARC"

You will receive a weekly report to this email showing deliverability metrics. 

3. Add TXT record to DNS

4. Once the TXT record has been applied (can take up to 24 hours), click Check Domain again to verify your domain. 

When all the records have been properly added to your DNS, your verified domain will look like this:

Important note! Once the sender domain shows as 'Verified' it won't refresh to the current status. This means that if your DNS records change any time in the future, we won't be able to tell. If you are experiencing deliverability issues while the domain is verified, we suggest you check your DNS records are still in place.
