Before you can start sending emails through the email marketing tool, you must first authenticate your domain, set up an SPF record to enable the best possible delivery performance, and add a user email address to send "From".
To get started, click email marketing and then Domain Sender Setup.
Next, click "Add a Sender Address" and fill out the form.
Next, go to the domain page and look for the domain of the email address you just entered. Click the "View TXT Records" button and enter the information into two separate TXT records in your DNS.
Once you have added the necessary information either to your site or registrar, come back to the platform and click the "Verify" button. You should see the status go from "Error" to "OK." Please note that this could take up to 30 minutes to propagate - if it doesn't happen right away, give it some time and check again.
Once your domain show's "OK" you are now able to start sending emails using the email address you entered in the first step. You can also add new email addresses with the same domain and start using those as well without any further verification.
To set your records you will need to go to where you purchase your domain name from (Google domains, GoDaddy, Rackspace, etc.). You will enter these records in your DNS settings for the actual domain you are using for your email address, so if the email you're trying to verify is email@example.com, go to the registrar where you purchase tech-toolbox.net.
For entering your SPF record into your DNS, all you need to do is create a TXT record and use either the domain name itself or the @ symbol in the "Host" field, and then put the SPF record you copied from the platform into he "Value" field. Click save.
