In addition in the main-log I get:
28-09-2023 22:06:34 – ERROR – 7.9.4 – 80.5 MB/8 GB – [cron] > TNP_Mailer_Message Object
The weird thing is that sendgrid reports that all emails are delivered including the ones marked as error in TNP. I share the report screenshot with my clients (paid newsletter) so it doesn’t look great when there are 100+ errors and since i had hardly any errors in the past I really want to get this fixed.
Do any of you have a similar issue? Did you make progress fixing it?
Things I’ve done (that achieved nothing):
– changed API key
– updated everything again, tables etc.
– checked limits
– went through sender auth and everything related
– got in touch with sendgrid support (said they don’t report this error)
