Postiz vs Sender: at a glance
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.
What is Sender?
Sender rebuilt its email builder and grew workflow templates from 9 to 79 after the MCP launch.
Sender's autumn work is on the creation side of the product. The new email builder, in September, uses one flexible container for every layout. October took the automation library from 9 pre-built workflows to 79, with 5 industry collections, 5 new categories and 19 sequence types. Those follow August's MCP server and rebuilt subscriber import; the Capterra ranking post in the same week is marketing, not a release.

Postiz
2.5MKT AUTO
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.
Sender
2.5MKT AUTO
Sender rebuilt its email builder and grew workflow templates from 9 to 79 after the MCP launch.
◆ Current state
Sender's autumn work is on the creation side of the product. The new email builder, in September, uses one flexible container for every layout. October took the automation library from 9 pre-built workflows to 79, with 5 industry collections, 5 new categories and 19 sequence types. Those follow August's MCP server and rebuilt subscriber import; the Capterra ranking post in the same week is marketing, not a release.
◆ Where it's heading
The MCP server changed how data leaves Sender, and these releases cut the effort of getting campaigns in. Templates and a looser layout model both shorten the path to a first send, which fits Capterra's 'Best for the Tightest Budgets' label. The feed still mixes marketing posts with releases, so cadence overstates shipping volume.
◆ Prediction
More industry collections are the simple extension of the template library. Write actions on the MCP server remain the open question, since the entries still describe read access only.
