Reliable delivery of transactional emails with free account for more than a year I have been using Socket Labs for transactional email about a year now and email delivery has significantly improved. Only hotmail still seems to be a problem, but that may be due to my DMARC settings. And the best news: it is completely free, while still having a fully functional dashboard :-) Socketlabs is maybe not as popular as other transactional mail providers, but I am very pleased with them. The only reason that I don't give it 5 stars is that email batches of more than 100 emails are being delayed up to a couple of hours.

SCAM avoid it Probably worse service. They offer fake 40,000 free trial. After "sending" 4000 emails I downloaded csv with all sent emails. From that csv I realize that they sent only 158! Rest were duplicates. After I downloaded that file they just close my account without valid reason!! Avoid this is SCAM! On top of that when account is close all links are broken after. So all my subscribers got email with all broken links now!

We have used SocketLabs facilities in a non-conventional way We have used SocketLabs facilities in perhaps a non-conventional way and have been very satisfied with the service. The only issue we have had is that some of the devices do not work with the SMTP server for some unknown reason. We use SocketLabs SMTP service to send alarms and status of equipment in the field to those that need to know. In years gone by this was simple to do with virtually any SMTP server you had a relationship with and some even that you did not. This is no longer the case. We are a relatively low volume user of SocketLabs but are very glad that the service exists because there are very few options available out there today.

I'm very happy with SocketLabs I'm very happy with SocketLabs. Deliverability has been significantly higher than other apps I've tried. They employ specific strategies to prevent recipient mail servers from blocking our domain, thereby improving our sender reputation. Also I am impressed with their customer service. Their responses to my questions are always highly personalized and address my issues directly, not like some of the robo-responses you get sometimes from help desks. I would highly recommend SocketLabs to anyone.

I use SocketLabs to send out every-other-week emails to 10,000 alumni I have been sending out every-other-week emails to a high school alumni database that has a little over 10,000 addresses, and it is VERY easy to do using SocketLabs. Essentially I take a previous email I sent out, copy it, and then re-do it so that it meets my needs. Highlighting the posting of internet addresses and email addresses is quite easy. And the finished product always looks very professional. I would highly recommend anyone using SocketLabs if they are sending out mass emails to thousands of addresses!
