Mailmeteor vs SendPortal: at a glance
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 SendPortal?
SendPortal resurfaces with a v4 patch release, its first tag since 2020.
SendPortal's last tagged release before this month was v1.0.3 in July 2020. On October 22 it published v4.0.0.1, which fixes sp:install skipping migrations on fresh installs and a route-caching failure from a duplicate logout route. The changelog link implies a v4.0.0 release just before it, which isn't in the tracked entries.

Mailmeteor
3.8MKT AUTO
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.
SendPortal
2.5MKT AUTO
SendPortal resurfaces with a v4 patch release, its first tag since 2020.
◆ Current state
SendPortal's last tagged release before this month was v1.0.3 in July 2020. On October 22 it published v4.0.0.1, which fixes sp:install skipping migrations on fresh installs and a route-caching failure from a duplicate logout route. The changelog link implies a v4.0.0 release just before it, which isn't in the tracked entries.
◆ Where it's heading
A major version followed by fixes to the installer suggests the project is active again and new installs are being tested. With two tagged releases six years apart, there's no cadence to read yet.
◆ Prediction
If v4 is a real revival, more point releases should follow within weeks; another long silence would mean v4 was a one-off.
