I require a way to add individual identifiers when sending emails in batches with Mailgun to track opens accurately.
def batch_dispatch(email_sender, recipient_tags, plain_content, html_content):
for recipient, tag in recipient_tags.items():
print(f"Sending to {recipient} with tag {tag}")
I’ve found that using Mailgun’s recipient-variables really aids in assigning unique IDs during batch sends. In one project, restructuring the API call payload to include a JSON map of custom IDs to recipients allowed detailed tracking without cluttering the email headers. This method ensured that each email could be uniquely identified for open and click analytics when referenced back to our database. It took some initial setup to convert our existing recipient list into the required format, but the post-implementation metrics clarity has been invaluable.
An alternative approach I have successfully implemented involves using custom headers to embed unique recipient identifiers. In one project, rather than modifying the recipient-variables payload, we appended an X-Unique-ID header on each individual email. By doing so, Mailgun captured these identifiers during event processing which we then matched with our internal records. Integrating this method with Mailgun’s event web hooks streamlined tracking opens and clicks without complicated payload restructuring. This strategy simplifies debugging and log correlation, proving to be both efficient and reliable for batch sends.
