What is a postmaster and how does it work?

Postmaster is a tool for in-depth mailing analytics. The postmaster can talk about the reasons why emails end up in spam. It finds delivery errors, monitors domain, and IP reputation, and monitors the sender's spam rating.


All major providers do everything possible so that users do not receive unnecessary advertising and spam. Everyone has their own rules, and they are constantly changing.


The postmaster also helps to monitor the reputation of the sender: the higher it is, the more likely it is that letters will reach the recipients.


Reputation is made up of two components:


- the reputation of the domain from which the mailing is carried out;
- the reputation of the IP address from which emails are sent.


How postmasters of different mail services work.


Unlike mailing services that show statistics on all sent letters, postmasters work differently. Most mail services have their own postmaster.


Before registering as a postmaster, you need to prepare. Check if the domain has DKIM, DMARC, and SPF records. If not, write down - without them, the postmaster will not be able to work at full capacity.


Why do you need to configure SPF, DKIM, and DMARC?


Further, the process is approximately the same for everyone:

- register or log in to the postmaster;
- add a domain;
- confirm the right to own the domain;
- look at statistics and draw conclusions.
