Sendy, Amazon EC2 t2.micro: 50 emails a second

Screenshot 2017-07-09 10.53.42

Now that my main email group has over 5,000 members I decided to see if I could 1) get Amazon SES to up my sending rate and 2) whether an Amazon EC2 t2.micro could keep up with 50 sends a second.

The previous send rate was 20/sec and it seemed just fine and wasn’t such a problem, but as the list grows 50 seems much useful.

So the good new is that according to watching the status updates as a campaign goes out, and eyeballing the per-second updates, the t2.micro kept up really well and I’ll keep the rate at 50/sec going forward.

So Amazon EC2 t2.micro, sendy.co and Amazon SES is a really good cheap option for running a decent sized email list.

    Hi David, great post, that’s a very interesting setup for sending emails. I have one question, though: When you use the combination of Amazon EC2 t2.micro, sendy.co and Amazon SES, do you need to pay separate outgoing data transfer costs to Amazon or is the email related data transfer included in the EC2 t2.micro + Amazon SES pricing? Amazon’s pricing looks a bit confusing to a newcomer… Thanks, Tom

    1. Actually I’m not sure but I have never seen any transfer costs associated with my usage of Amazon SES. I have seen very small charges when moving AMI files around – they are many Gb in size – but nothing I can attribute to the relatively small email transfers.
