MailBeez
MailBeez V5 arrives with a redesigned workspace, dark mode and V5-ready modules.
A side-by-side editorial comparison of Postiz and SalesBlink — release velocity, themes, recent moves, and the top alternatives to consider.
Postiz encrypts channel tokens and lets agents send connect links for new channels.
Postiz's November 13 release encrypts channels' access and refresh tokens in the database when enabled, with a local key or AWS KMS, and needs no migration. A new connect link endpoint and MCP tool let an app or agent give someone a one-hour link that adds their social channel to a workspace. It also fixes two access-control holes (billing routes open to plain members, and post saves across organizations), adds Amazon SES for email, and fixes 40+ provider and billing issues.
SalesBlink rebuilds warmup, binds AI emails to brand guardrails, and connects to ChatGPT.
SalesBlink is a cold-email outreach tool that now ships monthly roundups on top of individual launches. October brought out-of-office rescheduling, a Business Profile whose guardrails AI-written emails must follow, a rebuilt warmup engine that adapts ramp-up to spam placement, and ChatGPT and Perplexity connectors over its OAuth MCP server. It follows September's Outreach and Reply Agents and a faster Inbox.

Postiz still ships large releases about every six weeks. The last three have moved it from a scheduler toward publishing infrastructure that other software and agents can drive, with MCP access, preview comments and now connect links. This release adds the security work, encrypted tokens and tenant isolation, that larger self-hosted and multi-organization deployments need.
The next release will likely extend connect links to platforms that need API keys or instance URLs, and keep tokens out of Temporal history, which this release describes as groundwork.

The product is layering AI writing and reply handling on top of the developer surfaces (API, MCP, CLI) it built in August and September. Deliverability is the other constant: warmup, sender-health alerts, overlap warnings and one-click unsubscribe all aim at keeping volume out of spam.
Expect further Outreach Agent controls, which September's roundup promised for October, and more actions exposed through the MCP connectors as they reach more assistants.
