What is Mailmeteor?

Mailmeteor pushes past simple mail-merge toward AI assistance and serious-sender deliverability.

Mailmeteor is a Gmail-native mail-merge and outbound tool that has spent the last year expanding on two fronts: AI assistance across the mail lifecycle, and deliverability infrastructure for higher-volume senders. Recent releases add a Deliverability Hub for sender-health visibility and Inbox Rotation for spreading campaigns across multiple accounts.

What is Postiz?

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.

Mailmeteor pushes past simple mail-merge toward AI assistance and serious-sender deliverability.

◆ Current state

Mailmeteor is a Gmail-native mail-merge and outbound tool that has spent the last year expanding on two fronts: AI assistance across the mail lifecycle, and deliverability infrastructure for higher-volume senders. Recent releases add a Deliverability Hub for sender-health visibility and Inbox Rotation for spreading campaigns across multiple accounts.

◆ Where it's heading

Two throughlines are visible. AI has grown from a July 2025 writer (Sheets, Gmail, Dashboard) into a January 2026 reply assistant, moving Mailmeteor from 'send campaigns' toward managing the whole conversation. In parallel, deliverability tooling — warm-up bundled into Pro, then the Deliverability Hub and Inbox Rotation — is repositioning the product for 'serious senders' who need sender health and scale, not just personalization.

◆ Prediction

Expect deeper deliverability tooling (reputation monitoring, per-sender analytics) building on the Hub, and continued extension of the AI assistant from replies toward more of the send-and-follow-up loop.

2.5

Postiz encrypts channel tokens and lets agents send connect links for new channels.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.
