Attaching your own domain

Rumailer service clients can use their own domain for newsletters. In order to attach your own domain you need to contact the administrator of the service.

To verify your domain you need to do the following:

1. Create an SPF record

Although many DNS editors allow the creation of an SPF record, it is recommended that the SPF record be entered as a TXT record.

How do I create an SPF record?
If you create an SPF record, you will most likely see a form with at least two fields: “Host” or “Name” and “Value”.

Here's what you enter under these fields:

Host/Name: @

(Yes, you put the @ symbol under the category host or name. @ Means that the record is given on your own domain. Some editors will need the " @ " symbol, some will need to enter their own domain, others will not allow you to enter anything. Each DNS editor is different - you may need to contact your hosting provider for information on how to enter this record correctly).

Value: v=spf1 a mx ~all

Check if there are any other SPF records in your domain's DNS. For each domain there can be only one SPF record, so if it exists, just add this record:

For example, if your domain already has the record:

v = spf1 a mx include: ~ all

Then you just need to add:


The final record will look like this:

v = spf1 a mx include: include: ~ all

2. Create a DKIM record

Create a TXT record and enter:

Host/Name: api._domainkey

Volume: k=rsa;t=s;p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCbmGbQMzYeMvxwtNQoXN0waGYaciuKx8mtMh5czguT4EZlJXuCt6V+l56mmt3t68FEX5JJ0q4ijG71BGoFRkl87uJi7LrQt1ZZmZCvrEII0YO4mp8sDLXC8g1aUAoi8TJgxq2MJqCaMyj5kAm3Fdy2tzftPCV/lbdiJqmBnWKjtwIDAQAB

There can be multiple DKIM entries in DNS settings. You can create as many entries as you need.

In some settings field DNS Host/Name may require you to enter is your domain name).

3. Create a DMARC record

Create a TXT record and enter:

Host/Name: _dmarc

Volume: v=DMARC1;p=none;pct=100;aspf=r;adkim=r;
