MailChimp has decided to effectively kill the Mandrill service... Time to spend hours moving to a new outgoing email provider 😭

I'm going to try Mailgun.

Have you considered Salesforce Marketing Cloud?

This is where abstraction comes in handy as it would allow you to drop new services in with little effort.

Good point on abstraction/dependency injection. Definitely makes it a lot easier to replace a dependency in a scenario like this.

Lot of our clients gonna break 🙌🏼

@localhost +1, almost 50 clients that will have issues here. But I'm not even worried. Because I always advise them to use our SMTP (we've a solution for transactional email) but they liked Mandrill because it has a free option.. and you know "it's a new business we don't want to pay."
