Definitely the better listserv for WordPress

When it comes to listserv plugins for WordPress, there are just two choices: Mailing Group Listserv and WP Mailster. I bought the first one and ran into limitations and problems. A major limitation was that it didn’t offer CSV imports and exports. A big problem was that the cron-job created new php files in my public_html directory every five minutes. It was horrific.

WP Mailster, on the other hand, handled CSV imports and exports, had a great, well-organized interface, and handled cron-jobs invisibly through their included service. Support has been first rate. Mailster costs more, but it’s worth it.
