FAQ
Frequently asked questions about this comparison
Is Conveya also ISO 27001 certified?▾
No. Conveya runs EU-hosted, but we do not claim ISO 27001 certification. Watermelon is ISO 27001 certified. If that certification is a hard requirement in your procurement, factor it in.
When does Watermelon's per-conversation pricing get expensive?▾
A conversation counts as all messages within 96 hours. At high volume or with many separate questions, that adds up, with overage of €25 per 250 conversations on top of your plan. Conveya's fixed plans with included minutes are more predictable then.
Does Watermelon do telephony too?▾
Watermelon lists phone as a channel, but the product started chat-first. Conveya comes from AI telephony, so if voice is a core channel for you, that is the clearest distinction.
