A sending domain is a domain name used in the "From" address when sending emails. It is part of the email address that indicates the source or sender of the email. For example, in the email address "user@example.com," "example.com" is the sending domain. It personalizes your emails and helps recipients recognize them as legitimate communication from your business.
To set up sending domains, you don't need anything extra. You don't even need to bring your own SMTP credentials; we handle everything for you, so there are no additional costs.
Using a custom sending domain benefits your business by enhancing professionalism and business recognition, improving email deliverability through authentication (SPF, DKIM, DMARC), managing your sender reputation, and increasing security by reducing phishing risks. This consistency also builds customer trust and ensures your emails reach their intended recipients.
