I have a two sided marketplace connecting fashion models and clients - https://anotherstorymodels.com - all is going swimmingly so far, aside from an annoying bug with emails.
I’m using Sendgrid to send transactional emails between models and clients. I have also set up a messaging tool to connect to the users personal email inboxes using Sendgrid as the email processor. Long story, but this a temp solution.
Some users are expressing problems sending emails. For most it works, for some it doesn’t. Email addresses have been checked. Both my live and test accounts work perfectly. Here’s an example of an error message and log displaying a problem connecting to Sendgrid.
