Campaign Monitor vs SendPortal: at a glance
What is Campaign Monitor?
Campaign Monitor layers AI assistants throughout an aging email-marketing product to keep agencies on the platform.
Campaign Monitor (a Marigold product) shipped a batched update of small features: AI Email Booster for one-click campaign optimization, Segment Mapper for natural-language audience building, an updated Assistant with new pre-send reminders, a Signup page template gallery, a new Help menu, and a default sending domain to satisfy Google/Yahoo authentication requirements. APIs for agency client management were broadened in parallel.
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.

Campaign Monitor
1.3MKT AUTO
Campaign Monitor layers AI assistants throughout an aging email-marketing product to keep agencies on the platform.
◆ Current state
Campaign Monitor (a Marigold product) shipped a batched update of small features: AI Email Booster for one-click campaign optimization, Segment Mapper for natural-language audience building, an updated Assistant with new pre-send reminders, a Signup page template gallery, a new Help menu, and a default sending domain to satisfy Google/Yahoo authentication requirements. APIs for agency client management were broadened in parallel.
◆ Where it's heading
The product is in catch-up-and-defend mode: AI assistance gets layered into workflows that competitors (Mailchimp, ActiveCampaign, Klaviyo) have already AI-ified, while the agency angle — multi-client management APIs, new client settings layout — keeps Campaign Monitor differentiated for resellers. Compliance work on sender authentication is table-stakes deliverability. Few of these moves break new ground; together they signal a focus on retention rather than category redefinition.
◆ Prediction
Expect the natural-language pattern from Segment Mapper to spread to other builder surfaces (subject lines, send-time selection), and the agency API surface to keep growing. Don't expect a foundational architectural rewrite from this team.
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.
