There is a large database of email addresses (also phone numbers). It is necessary to organize a mass mailing of initial promotional emails to these contacts. Since the mailing will be to cold databases, meaning not to verified addresses, it is necessary to select and configure SMTP servers for warming up and sending emails. Accompany the mailing, analyze statistics - how many were sent, opened, how many ended up in the SPAM folder...
With registered, verified users, further set up automated mailing through the Brevo email service.
In the first stage, if there is experience working and sending emails using the Amazon SES service, to confirm technical skills it is desirable to conduct a test mailing to 20K addresses. The template, email design is available and will be provided!
The next stage is to set up your own SMTP servers and send emails. We will consider your recommendations on the scheme and infrastructure of the mailings!
