Lord, tell me, please, at the expense of the ability to conduct their own e-mail lists.
The situation is suchthat all authorized users of the service every day I send out a letter, which they subscribed and confirmed the subscription.
Because they are afraid to get into the spam lists, decided to take advantage of specialized services.
Of the main requirements for the email service — it's an open API so I could send a personalized message depending on user preferences, to selectively form the content of the letter from the database.
So far have found only one similar service — UniSender.
While less than 10 thousand users, the cost of this service is not substantial as$ 200 a month, but as you increase the number of subscribers costs can increase dramatically.
The resource lies on Amazon EC2
In fact, the questions I wanted to ask you:
1) what alternative mailing services with open APIs can recommend me (overseas)??? Criteria — reliability, convenience, price.
2) whether such services can protect me from getting spam lists and if it hits, can solve this problem, like report it?
3) how to do a mailing on their own to their servers, not to get into spam lists? what specialists are needed for this? and is it possible to solve the problem in the case of getting? (I would be grateful for links to a detailed discussion of these issues)
4) when getting into the spam mailing list to determine letters by IP address from which the letters come, domain or something else? does the content of the letter to polecenie it as spam?
Thank you in advance for your help!
