- Using Postie out in the Wild
Had a mixture of a "proud dad" moment and utter confusion today. Used my Postie email as the basis for testing a service today. As part of testing the completed upgrade from PHP7.4 to 8.5 I had to complete e2e testing of the functions of this clients CRM including checking that all their automations and integrations with external services were working.
With this client when a person fills in an information form on their website it gets sent to the CRM and then the customer gets added as a subscriber to their Aweber external marketing service and is added to their "welcome" email list. On the CRM as they progress through the different stages like "follow up" the CRM sends out APIs with "update customer tag x and put tag y" and this places the customer in a different email campaign.
I don't know whether it was an Aweber issue but while testing using my standard emails it added me to the subscribe list and then unsubbed me 2 seconds later. I thought it was my fault when setting this up on the Aweber side instead of deleting my test email it unsubbed it meaning that no emails could be sent at all...Tried again with other emails and no joy.
Looked at the subscribers list and no issues so I thought I can't use any email I previously used... what can I do.... POSTIE!
Used a Postie Alias and it worked fine. Used another and it still worked. Amazing! It's not me going mad. It's not my code changes or the migration from PHP7.4 to 8.5 Success!
To cut an already super long story short Postie came to my rescue, rendered everything properly and "just worked". "Proud Dad" moment for sure! But also.... what is going on with Aweber and my previous test emails... fair if they're rejected but it should say not just like auto-unsub 0.25 seconds after being added.
