Sender-level reputation controls and automated responses help isolate abusive activity before it affects other users. The API offering includes delivery webhooks, templates, subaccounts, suppression lists and transaction logs. The current pricing page says API delivery uses shared IP pools; dedicated IPs are not a generally available plan feature.
Outbound Filtering and Email API have separate volume-based pricing. The API free tier includes up to 100 emails per day and 3,000 per month. Usage counts recipients and attempted deliveries, including deferred or rejected attempts. Delivery pauses when a plan limit is exceeded, so applications should account for limits when estimating capacity.
Published customer stories name DreamHost, Rebel.com, 1-grid, XXL Webhosting, Wowrack, DiscountASP.NET and InterServer. The cases cover shared sending reputation, blocklist problems and email delivery support work.
