Expert help
Templates, data feeds, lists, personalization and deliverability, plus a second pair of hands for a stretched team.
Sailthru help, custom builds and integrations.
Sailthru, now part of Zeta Global, powers newsletters at large media companies. We help publishing teams run it, extend it with custom data and tooling, and connect it to the systems around it.
The opportunity
Where Sailthru shines, and where we come in.
Sailthru does a lot well. The opportunity is in the work around it: the hours spent by hand, the revenue it does not handle and the data that never connects.
Where Sailthru shines
- Built for media companies sending at scale
- Personalization driven by content and behavior
- Zephyr templating and data feeds for dynamic newsletters
Where we come in
- Templates and feeds need specialist knowledge to change
- Sponsor operations and ad workflows sit outside it
- Teams often depend on a few people who understand the setup
