sparkpost

This old old old old plugin doesn't work with WP 5.5.0. You get the following response in API mode: Response body: { "errors": [ { "message": "invalid data format\/type", "description": "field 'content.headers' is of type 'json_array', but needs to be of type 'json_object'", "code": "1300" } ] } Maybe now they can update it and also fix the broken logo on the admin page.

I used SparkPost for a while, they regularly disabled my account for no reason. The first time it was because I migrated a site from a dev area to the live domain, and forgot to change the sending domain. For that "offense" they totally canceled my account, and banned my email address, with no way to get it back. The second time they never told my why they deleted my account (new email). The just... did. I never spam, my sites barely use email for anything other than user forms. Sparkpost is a terrible business, I highly recommend you find another service instead.

2 reports of emails not being sent by different clients this week. One ended up working by removing the Mark emails as transactional check mark, and the other one just won't work anymore. Looking for another service. Disappointed to see such a HUGE company not keep their plugins up to date.

SparkPost lets your website use their servers to send your website's transactional emails. They have outstanding logging and are the best solution I've found. This is one of the first plugins I install on EVERY site I work with. Outstanding!

Plugin works well. Doesn't slow anything down. I get an error related to the debugging though: WordPress database error Too many keys specified; max 64 keys allowed for query ALTER TABLE sp_email_logs

It added +5 seconds on checkout and wherever emails were sent.
