Para você e seus agentes. ### Gerencie eventos de entrega. Verifique assinaturas de webhook com o SDK e então atue sobre os eventos de entrega. ### Tente novamente com confiança. Tente novamente com a mesma chave e corpo para recuperar a resposta original.

Find the answer. Search the email log by recipient or message ID. Open the message to see its delivery history, including deferrals and bounces, then use signed webhooks to bring those updates back into your application. [Email analytics](/email-api/features/analytics) [Delivery webhooks](/docs/guides/email/events) [Inbox placement](/email-api/features/inbox-insights) ## Transactional email, explained. ### What is transactional email? Transactional email is a message a customer expects after an action: a password reset, purchase receipt, booking confirmation or account update. Your application sends it to the person involved. Newsletters, promotions and audience campaigns belong in Email marketing. ### Can I use SMTP instead of the API? Yes. Bird SMTP and the Email API use the same sending infrastructure, domain verification, suppression handling and reporting. Choose the submission method your application supports. ### Does delivered mean the email reached the inbox? Delivered means the receiving mail server accepted the message. Inbox Insights measures inbox and spam placement separately through seed accounts and a measurement panel. ## Escale sem perder o controle.
