@Rjs37 I wrote them an email, they basically referred me here: here.
As you wrote, the price of block is going down but anyway, I did some calculations:
The company I work for had sent 7 million emails in January, and plans are more emails will be sent in future. We paid around 1100$ for that. Pretty good price if you ask me.
Now with their new policy, the same amount will cost us 2800$ (their cheapest blocks, 280 blocks for 10$).
How the frack should I explain that to management, that the prices for our email raised almost by 250%? Nope, I already wrote an email about explaining this and that we will be switching to different service, I picked MailGun, I calculated that it will cost us around 1500$ (with dedicated IPs) per month, but it's still better than Mandrill in future.
And yes, I need to rewrite our Mailer architecture, I wrote it that you need to swap only core class, bud MailGun doesn't support adding Google Analytics params to URL, so I need to somehow make that. Also new webhooks.
I'dont worry about the rewrite, the problem is how the ESPs will react if we start changing IPs of our emails, if they will be marked as spam we are delivering bad service to our customers, so that's what's bothering me. I need to buy some dedicated IPs by MailGun and begin slow transition of emails, type-by-type of email will be migrated, and at last our biggest type of email, newsletter, will be migrated.
I am pissed about this situation, but what can one do.
