PostRSS turns your RSS feed into social posts, not emails — so this list is a little different from the others. There’s no vendor here that does both well, and pretending otherwise would be misleading. What follows are the 20 real, actively-maintained tools that turn an RSS feed into an email newsletter or digest, split by who they’re actually built for.

This category splits cleanly in a way most auto-posting comparisons don’t. Publisher-side tools — Mailchimp, FeedBlitz, FeedOtter, MailerLite, Buttondown, ConvertKit, Beehiiv, ActiveCampaign, GetResponse, Constant Contact, and AWeber — are what you set up if you want to own a mailing list, send a branded newsletter under your name, and control when it goes out. Reader-side tools — Blogtrottr, Feedrabbit, follow.it, and Digest — work the opposite direction: an individual subscriber points the tool at your public feed and gets their own personal digest, with no setup or list-management on your end at all. If you want an official newsletter, look at the publisher column; if you just want to let visitors subscribe by email without building a list yourself, a reader-side tool (or simply linking to one) covers it.
PostRSS handles the social side of your RSS feed — auto-posting to Facebook, X, LinkedIn, Pinterest, and VKontakte the moment new content publishes. It doesn’t send email campaigns. The common setup for a publisher who wants both channels covered is PostRSS for social plus one dedicated tool from the publisher column above (Mailchimp or FeedBlitz are the most established) for email, both watching the same underlying feed independently.
No — PostRSS is built for RSS-to-social automation, not email. For the email side, pair it with a dedicated RSS-to-email tool like Mailchimp or FeedBlitz, both reading the same feed independently.
Mailchimp sends an official, branded campaign that you control, to a list you own and manage. Blogtrottr is set up by the individual reader themselves, pulling from your public feed into their own personal inbox — you never touch it and don’t own that subscriber relationship the way you do with a Mailchimp list.
Linking to a reader-side tool like Blogtrottr or follow.it from your site lets visitors set up their own email subscription with no work on your part, though you won’t own that subscriber list the way a publisher-side tool like Mailchimp lets you.
RSS-to-email isn’t one category, it’s two: owned newsletters you build and send (Mailchimp, FeedBlitz, MailerLite, and similar), and reader-initiated digests you don’t manage at all (Blogtrottr, follow.it). Neither is what PostRSS does — PostRSS covers the social side of the same feed — but running a dedicated email tool alongside it is a natural, low-effort way to cover both channels from one source of truth.
