React to incoming messages
Use webhooks to notify your app when an email arrives, then retrieve its content and attachments.
Inspect what was delivered
Open the received message, headers and raw content when a workflow needs debugging.
Keep the received message within reach.
Look beyond the send event. Open an email in the dashboard, inspect its final content and use the API to retrieve the fields your application needs.
For invoices, orders and support messages, add AI extraction to turn email and attachment content into structured records.
Turn incoming email into data
Test the send before your customers depend on it.
Pair your email workflow with inbox placement testing, domain checks and device previews. Check where a test lands and how the message looks before releasing a new template or changing a sending service.

How to bring a workflow into MailSlurp
Create an inbox and connect your app
Start with an address in the dashboard, then use the MailSlurp API and SDK guides to create and manage inboxes from your application.
Send a representative message
Test the confirmation, receipt or reply your app depends on. Inspect the delivered email and verify any domain settings required for your sending path. Plans show the current sending allowances.
Automate the next action
Configure a webhook or wait for the expected email through the API. Check the content, extract the data you need and continue the workflow with a repeatable test.
Follow your first confirmation from app to inbox.
Follow the message and its reply
Create a test address, trigger the confirmation in your application and inspect what arrives. Read the subject, sender and body, then open the verification link and check the application outcome.
Move one complete customer journey first
When moving a workflow from SendGrid, map the send payloads, inbound handling and webhook events your app uses. Test one representative journey first, including reply handling and domain configuration, before moving the next. Use the SendGrid comparison to check the sending, receiving and testing capacity your team needs.
Questions before you switch?
Where should I start when moving a SendGrid workflow?
Choose one email that has a clear next action, such as a confirmation link or a reply. Configure the MailSlurp sending path, create a controlled recipient inbox and trigger the message from your app. Verify its content, complete the action and check the inbound event before moving the next workflow. Start with sending and receiving.
Can I receive replies and attachments?
Yes. Create an inbox, receive email and retrieve its content, headers and attachments through the API. Use webhooks when your application needs to react to incoming messages.
How do I evaluate a migration?
Map your existing send requests, inbound routes and event handling. Try one complete workflow with a representative message and reply, check domain configuration and current plan allowances, then expand after the first flow works.
Bring your next email workflow into MailSlurp.
Start with an inbox, a real message and the next action your app needs.
