Bulk, but not mass mailing (up to 1000 emails per day), is it possible?

Question

Email

I'm getting ready for the ICO. As part of this complex undertaking, I am considering implementing an email company, among other steps. This is not a mass mailing of the same type of messages, this is a unique appeal to a person, either a CEO or an investor. The appeal takes into account the type of activity of the person, in one way or another there is a mention of his company and some possibility of cooperation. The appeal is checked for uniqueness in the copyright analyzer. But the difficulty is that this appeal should be sent only during the ICO period of the company.
I would like to receive some recommendations on how to properly organize this work. How to send a large volume of unique emails in a limited period.

Answer 1

mail service + templates or in general the
mailchimp API and similar
ones are even better - high penetration mail services, or at least mainstream ones that do not put gmail in subfolders

Answer 2

In your case, one way or another, you will have to use the API of one of the mail services, because. you need emails that are unique in terms of content. Typically, services allow you to create a letter template, and then add personalized content to it using context variables.
You can try mailhandler.ru , mailgun.com , mailchimp.com .
