How to implement a huge e-mail newsletter on your own?

Question

Email

There is a database of emails for more than 4 million people from my target audience.
I need to make a mailing list with a promotion, but mailing services require some insane money for this (from $20k)... How can I do it on my own?

Answer 1

If I understand the question correctly, then you are asking if it is possible to write such a mailer yourself.
If yes, then two sub-questions will appear here:
1) How to manage to send 4 million letters in reasonable time?
2) How not to get into spam?
Sending letters can be done in the usual bundle [hardware] + [program] + [sender]
Hardware - a good server with a wide channel
Program - you write on anything, even in php
Sender - configured postfix (you need to remove unnecessary checks, optimize queue settings, etc. .d.)
But how not to get into spam is a completely different question
In addition to the fact that there are certain requirements for signing letters (DKIM, SPF, DMARC), there is also a whole bunch of subtleties that relate to unsubscribe rules (FBL, List-Unsubscribe headers, etc.), domain rating, ip rating, etc. d.
4 million users is a very large base.
Judging by what you write, this will be the first mailing, so such a large send will seem suspicious to all mailers.
And the base is probably not cleaned (there will be many non-existent addresses, spam traps, etc.).
Therefore, with a 100% probability, it will not be possible to make a mailing with the delivery of 4 million letters the first time.
, you can do it on your own, but for a long time and quite expensive + you need a certain skill :)

Answer 2

If you need to make an inexpensive and bulk mailing, then it is better to use popular Email API services, such as Amazon SES or UniOne from UniSender.
Prices in both services are the same $1 = 10,000 emails. Deliverability is high. Amazon SES is aimed at foreign recipients of letters, UniOne has a high deliverability in Russia.
But since these are API services, then you need scripts or programs that not only send through them, but also collect statistics, and also process Bounces and spam complaints, unless of course you are a spammer :) For example , Newsletter + Software or similar, there are many of them.
