Migration FAQ
How hard is it to migrate from Twilio?
Most migrations take a few hours. Our API structure is similar to Twilio's, so the changes are minimal. We provide migration guides and can help you port your phone numbers.
Do you support all the same features as Twilio?
We support SMS, WhatsApp, and Email with all the features most developers need. We don't support Voice yet, but it's on our roadmap. Plus, we have features Twilio doesn't, like built-in AI agents.
What about reliability?
We maintain 99.9% uptime with redundant infrastructure. We use the same carrier connections as Twilio for SMS delivery. For WhatsApp, we're direct Meta partners.
Can I try before fully migrating?
Yes! Most customers run Zavu in parallel with Twilio first. Start with a subset of traffic, verify everything works, then fully migrate when ready.
Do you offer volume discounts?
Yes, for high-volume senders we offer custom pricing. Contact us for details on enterprise plans.
