Newsletter sending interupted

[michaelbrackenbury]

ZC V1.3.9g upgraded from previous version about 1 year ago.

We have a newsletter which sent to about 20 customers (green ticks) and then stopped with an SMTP error message relating to one email address. We removed this address in admin and then ran the newsletter again. This time it sent to about 200 customers and stopped again with an SMTP error for a different email address.

We have a total of about 2000 people that we wish to send to, but obviously do not intend to keep repeating the run or some people are going to get a lot of the same newsletters.

We are aware of hosting limits for emails/newsletters, but we are hosted with a ZC specialist company who helped us with the newsletter and knew what we intended to do, so we do not think a limit is the problem.

Any advice would be appreciated.

Ask them what their mail logs state

Thanks for the response - this is their reply:-

"Unfortunatly the newsletter function in Zen Cart will fail when sending if there are emails in the list that are not correct."

Can anyone confirm this.

Thanks

Precisely, what did their error log report??

If the email address is invalid and is immediately rejected when attempting to send, then yes, often the sending process will die.

There are many things you can do about that, including auditing for invalid email addresses, ensuring that you're really only sending your newsletters to those persons who have explicitly asked to receive the newsletter (and ensuring that the "default" is set to NOT automatically sign them up to the newsletter so that bogus accounts don't trigger these problems), and consider using a newsletter mailing service like Constant Contact or MailChimp if you intend to do regular newsletter mailings.

Thank you very much.

If the ZC newsletter facility falls over so easily, and as it is almost impossible to tell if all the email addresses submitted are valid, then we will go with one of the newsletter mailing services.

Thanks again.
