My website/newsletter has been very small so far so I just picked a plugin for newsletters (MailPoet) that seemed good and had a free tier. But I just started a membership style program - it's free, but I have newsletters that go out every week. People who sign up for the program after the newsletter for that week has already gone out have no way to receive the newsletter after it's been sent out. Is there a better newsletter plugin that would allow me to resend them - or better yet, automate it so people who sign up via a certain form will automatically receive all the past newsletters from the program? MailPoet says you can do that with the paid tier, which is fine, but when I look at their website and compare their tiers, the features of each tier are nearly identical, so I don't know if I trust that I know what I'll be getting by paying (ie is paying for the mid level tier going to get me what I need when the level comparison chart claims I should have it with the free tier?)

Missing the first newsletter was no big deal, but from now on I'll be using the newsletter to link to files that people will need, and I need to find a way that works to have people auto receive those even if they sign up late.
