Calling a provider API takes an afternoon. Making messaging dependable is a list of unglamorous problems that only show up in production — and that list is what we maintain so your team does not have to.
None of it is hard in isolation. Each item is discovered from an incident, fixed under pressure, and then maintained as providers change their behavior. Buying the layer is how that maintenance stops being your team’s problem — and how nobody gets paged at 3am for a provider’s rate-limit change.
Your application still owns the decision to send, the content, and the record that matters to your business. You can route some traffic through the layer and leave the rest direct — the accounts stay yours, so the choice is reversible at any point.
Every connection carries a send rate. The platform queues to that rate instead of firing as fast as a provider will accept, because the fastest way to get throttled is to send at the speed that causes it.
Read the guide →Sending is accepted asynchronously and there is no de-duplication key. Retrying a request you are unsure about sends a second message and bills for it.
Read the guide →We connect to the provider accounts you already pay for, and we never sell you message credits. That one decision sets your rate, your switching cost, and who owns the relationship — everything below follows from it.
Open →We chose to sit above the provider APIs rather than hold carrier relationships — because that is the arrangement that keeps your rates, your registrations and your sender identity in your own name. Here is what that choice puts in your hands.
Open →A single account is a single point of failure you cannot see breaking until customers tell you. Connecting a second turns that into failover you configure once — which is why routing belongs in the layer rather than bolted on later.
Open →Sending direct is the fastest way to send the first message. The layer is what keeps messaging dependable once a second provider, a second team or a second failure arrives — and it adds nothing you have to migrate away from.
