Rspamd 4.3 fixes SPF evaluation order and rejects weak DKIM keys, with results that change.
A side-by-side editorial comparison of RSS.com and Salesmsg — release velocity, themes, recent moves, and the top alternatives to consider.
RSS.com is adding reasons for podcasters to stay, from listener voicemail to a free academy.
RSS.com ships about one bundled release a month. The last two added listener voicemail (60-second browser recordings linked from every episode's notes) and a free Learning Center with 22 courses built from its own blog and video library. Last year's public API remains the biggest change to what the platform can do.
Salesmsg adds call-back requests and a one-click Emergency Stop for all outbound texts.
Salesmsg's autumn releases added survey automation, Click Tracking, upgraded Reviews and an official MCP server, then turned Sherpa AI into an assistant that sends replies and builds broadcasts after approval. The November 12 update moves to calling and safety controls: callers can request a callback instead of holding, Emergency Stop pauses every outbound message at once, inboxes can require call recording, tags can be applied during calls with HubSpot sync, and a weekly recap reports AI agent performance.

Last year's public API remains the biggest change to what the platform can do.
With hosting itself a commodity, RSS.com is competing on what surrounds it: audience interaction, education for new podcasters, and open standards such as Podcasting 2.0 tags. The API gives technical users a way to automate, while the academy and voicemail aim at beginners.
The entries show steady monthly releases but no clear next feature, so the specific next move is unclear.
Salesmsg's autumn releases added survey automation, Click Tracking, upgraded Reviews and an official MCP server, then turned Sherpa AI into an assistant that sends replies and builds broadcasts after approval. The November 12 update moves to calling and safety controls: callers can request a callback instead of holding, Emergency Stop pauses every outbound message at once, inboxes can require call recording, tags can be applied during calls with HubSpot sync, and a weekly recap reports AI agent performance.
With AI now able to send messages, Salesmsg is adding the brakes: an organization-wide stop switch and weekly reports on what its AI agents did. Calling features keep catching up with texting, with queue callbacks and recording rules.
Expect more controls over what Sherpa and AI agents may send, such as per-agent limits or approval rules, alongside further HubSpot call-data sync.
