Blocks API
Blocks happen when your email is rejected because of an issue with the message itself rather than an issue with the recipient's address.
There are several causes for blocked emails. For example, your mail server IP address may be blocked by an ISP, or the receiving server may flag the message content using a filter. Twilio SendGrid will not suppress future messages to blocked addresses by default.
For more information, please see our Blocks documentation.
You can also see your Blocks in the Suppressions settings menu of the Twilio SendGrid App.
Retrieve all blocks
GET /v3/suppression/blocks
Base url: https://api.sendgrid.com
This endpoint allows you to retrieve all email addresses that are currently on your blocks list. A maximum of 500 blocks will be returned per query. You can use the offset and limit parameters to retrieve more or less than 500 results.
Authentication
- API Key
Headers
The on-behalf-of header allows you to make API calls from a parent account on behalf of the parent's Subusers or customer accounts. You will use the parent account's API key when using this header. When making a call on behalf of a customer account, the property value should be "account-id" followed by the customer account's ID (e.g., on-behalf-of: account-id <account-id>). When making a call on behalf of a Subuser, the property value should be the Subuser's username (e.g., on-behalf-of: <subuser-username>). See On Behalf Of for more information.

default: NoneThe end of the time range when a blocked email was created (inclusive). This is a unix timestamp.
default: NoneLimit the number of results to be displayed per page.
default: NoneThe point in the list to begin displaying results. To retrieve more than 500 results, you can make multiple requests to the API, using the offset to begin at the next result in the list.
