- Free and Growth plans cap segments at 6 and 10, and reporting history at 30 and 90 days.
- SMS pricing is not published and requires a sales conversation.
- Reviewers mention unclear documentation for advanced cases and limited in-app design options.
Sendloop
Pros

- Supports marketing and transactional email in one account on every plan.
- The agency product, Studio, centralises the audiences of multiple clients.
- Offers an on-premise deployment and a managed deliverability service for high-volume senders.
Cons
- A competitor reports the blog has not been updated since 2021 and the X account since 2017, which raises questions about how actively it is developed.
- Independent reviews are few and mostly old.
- There is no public security or compliance documentation.
- Most integrations depend on Zapier rather than native connectors.
