What problems can the email marketing service have?

Question

Email

I have a database of email contacts.
I want to make a service for sending letters based on it, so that you can select the necessary contacts according to the parameters and send letters to them.
What difficulties might my service face? Probably, it is necessary to think over some proxies? Send per minute limits? How not to get into spam filters?

Answer 1

DKIM, PRT + IP warm-up + unsubscribe link + subscription form (needed for services if banned, it doesn’t help against mailers) + tracking the percentage of hits in spam

Answer 2

Vlad :@Sc0undRel: for starters, consider if it’s illegitimate (asked) - legal risks, for example ..
the simplest option is, as dimonchik2013 suggested,
I’ve been studying for half a year and the further the more, from sending a simple letter from soap to soap - a whole science has poured out.
The letter itself is only worth something, and the technique is one side, the technical algorithm is another, marketing is the third and...)))
How not to get into spam filters? - First here! You need to think not how not to hit, but what to do when you start to hit !!! There will be SPAM whatever they say. Little is written about it, but here's a spam bonus for you - buy a domain with TIC +10 - already increase inbox % 7-15. Such lying around is a gift.
DKIM etc. - it goes without saying.
The host needs the correct VDS current and further - otherwise you will use it to study, you will do a lot and you will be slammed
. we run through them. https://zomro.com
And do not buy any information business there like Shelest, there is a lot of money - information is water, almost everything is lying around for free, and what is worthwhile is in clubbing.
In general, depending on what task you have initially.
Simple vps gray purchased database, wordpress may mail and went quietly, they will block - new.
you will vary in order from 1/3 - solid spam but incoming and 5-12% SPAM with inbox. And drive the letters in a circle, change the host and don't think about anything .. :).
Well, lastly. There was such a sad case in St. Petersburg when company X sent an advertising letter to the antimonopoly service, a fine of 101,000 :) - the database needs to be cleaned ... :)
