“We have recently chosen Socketlabs as our SMTP provider because they are really professional, their services are good, fast and nicely supported by the Socketlabs team. The service is good because the emails sent via the SMTP are always delivered and there is a really nice web console where you can check the status of all emails sent. Their support is very fast to reply when you have a question.  It was also very fast and well documented to get up and running.  After investigating SMTP providers Socketlabs appeared to us as the best SMTP provider that fit our needs.  We are happy with them!”

“I have been fighting to get your competitor to work for months.... no phone number, just an awkward way to 'submit a ticket’. I signed up with you today and within 30 minutes I was up and running.
