What is a sending domain?

Sending domain, is the domain that is used to send emails. It is identified with the sender's email address in the 'From' field of the message. Furthermore, it can be a subdomain, it is not always the same as the store domain, e.g. store domain: store.com, sender domain: newsletter.store.com

Why is a sending domain important?

Sending domain acts as a brand identifier in the email world. It makes it easy for email service providers to distinguish your emails from potential spam. This, in turn, ensures that your messages go straight to inboxes instead of landing in the spam folder.

A sending domain is also a tool for monitoring and improvement. It allows you to track what emails are being sent on behalf of your brand and adjust your approach to communicating with your audience.

In a nutshell, sending domain is an investment in the long-term success of your online business and part of building strong customer relationships. It makes your emails easily recognizable, trustworthy, so they can even better represent the unique nature of your brand.

Can I use any address as a sending domain?

It's better not to use a regular email address. By using a sending domain, you avoid the pitfalls that can arise when emails are not uniquely associated with your brand. It's a kind of safeguard against your emails being mistaken for random spam. In a way, it is a key to accessing your customers' inboxes.

It is also worthwhile to use a subdomain for marketing communications, so that:

  • Negative reputation impacts directly on the main domain will be limited to the subdomain only;

  • It will become easier to monitor marketing communications conducted through the subdomain itself;

  • Simpler to work, control, minimize risks and take care of the security of the main and subdomains separately.

Keep in mind:

Domain registration - Make sure the domain you choose is unique and appropriate for your brand. It should be easy to remember, related to your business, and easy for customers to identify.

Taking care of your reputation - When sending emails from a new domain, it's a good idea to start with small amounts and gradually increase the mailing. This will help you avoid a sudden increase in activity that could negatively affect your reputation.

Taking care of security - Keep your domain secure by following DNS security best practices, using strong DKIM keys and taking care to protect your domain from abuse in general.

Remember that adding a sending domain is a process that requires attention and care. Correct configuration from the start will help you avoid problems with message deliverability and maintaining a positive domain reputation.
