Passendo ESP integration: 1 tag, billons of impressions.

Newsletter commercialisation with one simple tag

Passendo can easily integrate with your current ESP with a one-time tag that’s placed inside the email template in the ESP user interface.

Incremental revenue in a high quality environment

We help email communicators – like publishers, retailers and ecommerce vendors – build incremental revenue by placing value on their high quality channel

A lightweight tag that does all the heavy lifting

Easy integration for any template builder:

  • ESP-agnostic

  • lightweight HTML tag

  • once-off simple implementation

We work with all the world's largest ESPs and can facilitate an integration if we don't already support yours
