Easy to use, great support!

After trying another WP mailing list plugin and not getting it working (and getting very poor support) I switched to WP Mailster, and had a completely different experience. It was easy to set up, works well and integrates easily into our site.

When there was a problem about server limitations, Holger from WP Mailster was ready to help and sorted it out for me in a friendly way. I really recommend this plugin to add an email listserv to your WordPress site.
