You’ll be pleased to know that we’ve finally tracked down why some people were experiencing issues with Send Later.
A handful of our customers were using it on an industrial scale to schedule thousands of emails all at the same time. This was overloading our servers and causing everyone else’s scheduled emails to wait in a queue behind these few people’s newsletter releases.
The message from us? Please don’t use Send later for bulk email marketing or newsletters! We are not built or designed for that. (Neither are any other ‘Send Later’ enabled Gmail extensions like Boomerang.)
To make sure it doesn’t happen anymore, we’re going to put some (generous) limits on Send Later so that you can’t schedule so many emails all at the same time and make everyone else wait.
It shouldn’t have any impact on customers who use Send Later in a normal business context – only for those using it for mass email marketing and newsletter distribution. Apologies if that’s you. I’d recommend using a dedicated service like Mailchimp.
The limits will be in place by the end of the week (not that you’ll notice if you are using it normally) – after which, Send Later should be working like clockwork again.
We’ll post on Twitter when it’s done.
Sincere apologies to those of you who may have experienced some emails being sent later than intended.
