Bundle questions

What lifecycle stages does the Sonar bundle cover?

It covers welcome, verification, data connection, invitations, trial conversion, usage limits, receipts, payment recovery, password resets, feature launches, weekly digests, NPS feedback, win-back, and cancellation.

Does the Sonar design require custom fonts?

No. The templates use system-safe typography so the visual hierarchy does not depend on a web font loading in the inbox.

Can I change the colors and brand?

Yes. Open any template in the playground to edit its content and presentation, then export the updated TSX for your application.
