Mailchimp Transactional Email

Mandrill is a reliable transactional email provider, I've been using this provider for over 1 year and so far I don't have any problem with that. They also provide complete API documentation so we can easily connect to our project

The cost for email is quite high compared to their competitor. But I choose Mandrill because I think they are more reliable than the competitor

I run a busy social network. Around 6,000 users total, and 300-400 online at any given time. Due to this, I needed a transactional email service that had great deliver-ability for invitations, verifications, password changes, etc. Mandrill was recommended to me, and we were completely happy with the service. Unfortunately, when they bundled Mandrill into Mailchimp, we couldn't afford it anymore.

Unfortunately, bundling services did no favors. What previously was affordable for us no longer was. While the service is great, the way the change was implemented was sudden, leaving companies little time or recourse to find other options quickly. That solidified my decision to leave- most companies would grandfather in existing members, offer a lower rate, something. They simply provided us with addresses for other services, losing customers in the process.

MailChimp is easy to use. It's drag and drop feature is easy and it's Image Fix Up is fabulous.

They've recently gone beyond the core business of email marketing (for example into Facebook advertising) and increased the price accordingly.

Mandrill (now interated inside Mailchimp) has been a solid and reliable transactional email provider, with great delivery rates, very slow spam scores and ultra-fast reception speed. It provides useful and flexible reports and great dashboards too.

In order to keep it's spam reputation high it takes some effort to set up a new email domain in Mandrill. You have to prove you own the DNS and configure a SPF/DKIM record.
