Frequently asked questions

We maintain centralized suppression lists of complainers, bounces, and unsubscribes. Before you send, check addresses against these lists via our API to avoid sending to people who don't want your email. This prevents spam complaints and keeps your sender reputation healthy.

We integrate with SendGrid, Mailgun, Amazon SES, Mailchimp, Klaviyo, and HubSpot. We also offer a universal REST API for custom integrations with any platform.

Our API responds in under 50ms on average. We support batch verification for checking thousands of addresses at once, making it easy to verify entire lists before sending.
