Azure Communication Services Add Footer

Question

Azure Communication Services Add Footer

Richard 31

Is there any way to add a footer to all email that passes through our Azure communication service instance? We have a company footer we would like added to all externally sent emails. Thank you.

Thank you so much for your detailed explanations. So here is our exact scenario... We are moving away from Proofpoint as our gateway/spam filter to using just Microsoft. We have several internal SMTP relays (large org) for applications, server alerts, multi-functions devices etc to send emails outbound. When they send to external email addresses, those relays would send through our Proofpoint gateway which then added the company footer. Since Proofpoint is going away, we needed another email gateway for these internal relays to send through and that is where Azure ACS comes in. We've got it tested and it works well but we need that company footer added. These are Linux Postfix boxes so not sure I may can just add the footer there but I will definitely look in to doing it via logic app first. I'm going to give that a shot and let you know. Again much appreciate your insight here. Thank you.

Hi Richard,

As stated by Alex, there is no built-in way in ACS to add a footer to emails. However, you can still do that by implementing some kind of middleware that will be used to call the ACS.

That middleware can be a Logic App, Function App, or within your application

Like in this Python. example, the middleware could add the footer with something like this:

from azure.communication.email import EmailClient

def main(plain_text_content: str):
    try:
        connection_string = "null"
        client = EmailClient.from_connection_string(connection_string)

        # Define the footer content
        email_footer = "\n\n--- Sent from Azure Communication Services ---"
        html_footer = """
                <p>--- Sent from Azure Communication Services ---</p>
                """

        plain_text_body = plain_text_content
        html_body = f"""
                <html>
                    <body>
                        <p>{plain_text_content}</p>
                    </body>
                </html>"""

        full_plain_text = plain_text_body + email_footer
        full_html = html_body.replace("</body>", html_footer + "</body>")


        message = {
            "senderAddress": "DoNotReply@<from_domain>",
            "recipients": {
                "to": [{"address": "<to_email>"}]
            },
            "content": {
                "subject": "Test Email with Footer",
                "plainText": full_plain_text,
                "html": full_html
            },
        }

        print("Sending email...")
        poller = client.begin_send(message)
        result = poller.result()
        print("Message sent: ", result.message_id)

    except Exception as ex:
        print(f"An error occurred: {ex}")

if __name__ == "__main__":
    my_email_content = "Custom email body"
    main(my_email_content)

Hi @Richard
You can add a footer to emails sent through Azure Communication Services by utilizing the Footer property of the InteractiveMessage class. This property allows you to set the footer content, which can include emojis, markdown, and links. However, to apply a footer to all externally sent emails, you would need to implement this in your email sending logic, ensuring that the footer is included in every email sent out.

For organization-wide footers in a different context, such as Exchange Online, you can create a mail flow rule that applies a disclaimer or footer to all outgoing emails, but this is specific to Exchange and not directly applicable to Azure Communication Services.

Issue: Azure Communication Services Add Footer

Solution:Thanks everyone for their input. Using a logic app/function app would be preferable as outlined by Alex and others but that could get costly as millions of emails will be routing through this ACS instance a month. I've found a way to apply a company footer directly from my postfix servers (using altermime) that should work fine. Again, thanks to everyone for their input.

Answer 2

hi richard,

thanks for posting this one :)

u gotta understand that azure communication services is more about the transport layer its not a full-blown email marketing platform. but hey, we can get creative here.

for the microsoft way, u have two main paths

pre-processing with logic apps or azure functions u can hook up a logic app before emails hit the communication services. here's a quick example of how to append text to emails using logic apps

// in logic apps workflow actions: { "Initialize_variable": { "inputs": { "variables": [ { "name": "emailBody", "type": "string", "value": "@{triggerBody()?['body']}" } ] }, "runAfter": {}, "type": "InitializeVariable" }, "Append_footer": { "inputs": { "name": "emailBody", "value": "@{variables('emailBody')}\n\n---\ncompany footer text here" }, "runAfter": { "Initialize_variable": [ "Succeeded" ] }, "type": "AppendToStringVariable" } }

full docs on logic apps email processing https://docs.microsoft.com/en-us/azure/logic-apps/logic-apps-overview

post-processing with transport rules if u're using exchange online somewhere in your flow, u can set up transport rules to append disclaimers. not pure ACS but might work depending on your architecture.

now for some vendor-agnostic tricks that might help in other scenarios too

if u control the email sending code, just append the footer before sending. most email SDKs let u modify the body easily

for html emails, make sure ur footer is properly separated with  tags or similar

consider using merge tags like {{footer}} if u're doing templated emails

common pitfalls to watch for

footers might break html structure if not done carefully

email clients sometimes mess with styling

mobile rendering can be tricky

if u need more specific help with implementation, share which part of the flow u control - are u using the ACS email client SDK or the REST API directly? that changes the game a bit.

let me know if u get stuck

Best regards,

Alex

and "yes" if you would follow me at Q&A - personaly thx.
