How to implement mailing and processing of its results with little bloodshed?

Question

PHP

Necessary

• send an html email with text and a couple of images to a list of addresses
  
• Place several targeted links in the mailing list
  
• Track from which addresses what goals were achieved
  

There are 200 recipients. How can you do it as simply as possible, free of charge and not completely by hand?

Answer 1

If it's completely free, then send the mail function one letter every couple of minutes.
If it’s high quality, then use a mailing service like https://www.unisender.com/ru/
For 200 addresses, they will take some pennies from you there, plus there is an api
(not advertising if anything, there are a lot of such services, you can use any, google by "mailing service")

Answer 2

Yes, Unisender - it will come out a penny. If you want - write to us, we will give you a coupon for a discount. https://vk.com/unisender_hq
