User reviews and comments
Solution efficace et support réactif. Je recommande
So far my experience is extremely ignorant, lazy and helpless first line support basically doing nothing. One ticket resolving takes more than 1 week!
SendinBlue is terrible for support..
I had a very bad experience with Sendinblue
No more free plan since April 2016. :(
Update: managed to get second email confirmation working after being in touch with them via twitter, and decided to go with them due to mailgun's annoying company verification stuff which put me off.
I tried to add a second email to my account and it went straight into spam. Then the confirmation link inside didn't work (404). Then whitelisting my local domain didn't work, so now I'm stuck. Therefore, I have no interest in going any further as I can't be bothered waiting around for them to fix things.
We have used sendgrid as well as mandrill (MailChimp). Both have rock solid APIs and goof platform.
SendGrid, Mandrill and Mailjet are not the only transactional email providers with free plans. Can you open this table to other popular providers? (Disclosure, I work for Mailgun)
Thanks @loren, I have updated this comparison table accordingly.
MailChimp has a new SMTP service with a free plan now, called Mandrill (mandrill.com), and the STS product is being phased out. Let's get this comparison up-to-date! I've already added Mandrill and removed STS from the larger comparison at: transactional-emailing-providers-mailjet-sendgrid-critsend
