Question

I have a php mail script sitting on a LAMP vps server. The script grabs about 1000 email addresses and sends them each an html email.

I tested the script with about half a dozen of my own test email accounts and things worked fine. But I am concerned something may go wrong when I actually use this script for 1000 emails. Some things I would like to test for are

1) Confirm all 1000 emails were sent and received

2) Test to make sure emails did not end up in people’s spam folders

3) Detect any other general failures

Does anyone have suggestions on how I can test for the above cases? I would like to read about your experiences building batch email scripts.

Answer 1

You can use some kind of dummy SMTP Server. I Prefer :
Dumbster this small server written in java works like an normal smtp but stores the emails in the filesystem.

I think you cant verify that your mail is not marked as spam. Only solution is to provide a backlink wich the users has to click.
