Setting up Transactional Email

Generation of emails can be done through different mediums like applications, CRM, website or various other tools for campaign management. However, there is a need for integrating these apps through a relay server like SMTP or transactional email provider. Don’t worry!! It’s not as difficult as it sounds. Just a one-time effort is needed.

Following are the steps involved in setting up a transactional email:

1.DNS Set Up

There is a need for setting a domain for the transactional email through which emails will be sent to the users. However, it is important that such a domain is chosen with a keen eye. Also, it is recommended that transactional email is separate from the email for promotional marketing and hence a subdomain can be used for transactional emails.

The next step is to choose that the domain is authenticated with either or all the below authentication processes:

  • DMARC- It is one of the most critical parts of it. As it name suggests, the message sent across through domain is authenticated, reported and confirmed. DMARC helps not only in detecting but also preventing any email spoofing. Along with it, it also reports the sending out of any fraudulent emails from the domain.
  • SPF- SPF gives the permission given by the domain to the sending server ensuring that only defined IPs can send out the emails. Thereby, reducing the security concerns.
  • DKIM- This process of authentication focuses on digital encryption. The ISP servers recipient will decrypt the email thereby ensuring that the email is not coming through an untrusted source and no tampering of content has taken place.

2.SMTP Credentials-

After the domain is set up, the next step is of integrating the application through the protocols of API or SMTP. Some of the information needed for initiating of sending mails requires the following details:

  • SMTP username and a password
  • Hostname
  • SMTP port

3.Sending out

The content set should be simple and only relevant images or HTML should be added. Just don’t confuse transactional email with promotional emails and you are good to FLY!
