Good email service?

Question

Email

Please tell me the mailing service, or where to get smtp for mailings? you need to make a small mailing to your customer base (only 800 customers)
Large services are blocked due to supposedly spam ... no matter how I explained to them that these are my customers, they do not believe ..

Answer 1

Because:
- how do you prove that these are actually clients? Other than "I swear on my mother"?
They simply want money.
In general, everyone wants money - and spam services too. They will send it to your Spam folder for free :)
PS: If these are actually clients, with confirmed soap, put your mailer

Answer 2

Are you sure that formally you definitely do not have spam?
unsubscribe is and works?
are the headers required by rfc5322 present?
ptr, spf, dkim, dmarc - is it all configured?
how fast do you send? (letters per minute)
There are great proven services - mailchimp, sendgrid etc... use them or hire an admin.

Answer 3

See SMSC:
E-mail mailing list
E-mail server for software integration

Answer 4

Own mail server www.mailout.ru . If the distribution is really for subscribers.

Answer 5

No one will send spam. If these are really your clients, then mailchimp and esputnik will send out mailings for free, but both of them have fairly strict moderation, and if it’s still spam, then you only have your mail server as suggested by Dmitry Simple , but here it’s already on your fear and risk.
