How to make a one-time mailing to the database of 7000 addresses?

Question

Email Marketing

Hello. I got a database of ~ 7000 addresses to which I need to make a mailing list. The subject of the letters is harmless - children's contests, in fact, the entire database is the previous participants who need to be notified about the start of a new contest. What is the easiest way to carry out such mailing without using mailing services, so as not to go into spam? Or what service would you recommend?

Answer 1

It can be done in MS Word, it just needs to be a file with a database and a template, then mailing. Maybe this link will help

Answer 2

No...
Or send <100 messages per hour to each mail service.
>30% RuNet boxes on mail.ru, so think how much time is needed for this...
MailGUN - free tariff up to 10,000 messages per month. Excellent deliverability on mail.ru, google, homail c aol. rambler and yandex are not a problem in general.
