Error handling on Logic App with SendGrid connector

Hi @Kour, Amandeep Greetings! Welcome to Microsoft Q&A forum. Thank you for posting this question here.

Some of the Logic App triggers and actions have an option to enable the Retry mechanism. For example, an HTTP action has the following option which can be found under the action settings

You can try and find a similar setting in either the trigger or the actions in your workflow and can try to configure this setting. You can refer the section Retry policy types for different options available.

Is there any queue mechanism to handle such error

There is no out of the box mechanism available other than the above-mentioned option to facilitate the retry mechanism.

However, you can consider designing an alternate workflow which gets triggered when an action such as SendEmail fails and perhaps queue the events to a different end point such as Service Bus queue and process them later. Refer the article Change "run after" behavior which provides more steps on how to implement this parallel work flow. You can consume the events of the Service Bus queue later from the branch when the SendEmail succeeds.

Alternatively, if you connector supports Batch messaging, you can consider adding the failed messages to a Batch and send them as a Batch. Please refer the article Process Batch messages in Azure Logic Apps for your reference

Hope this answers your question! Please let us know if you need any additional clarification on this.
