Bulk email sending using email communication services

NAHID M A 0

I am creating a backend application in go. I want to send bulk emails and I was thinking about leveraging the use of azure communication services for it. But I didn't find any packages for go. Is there any Go packages available for integration of azure communication services?
I would also like to know more about the pricing, recipient limit, and resend options that are available in azure communication services.

Is there any other service available in azure such that we could dump the email list and body to the azure and it will handle the queue and other handling works. Like we could see the dashboard and view the stats about it. I am expecting for this service an API to send the bulk list of email ids and the template.
I heard about send grid but can it be integrated with azure.

@NAHID M A Thanks for posting your question in Microsoft Q&A.

ACS email Service supports sending bulk email send options and different features as well

Currently Email service in Azure communication service SDK support for these languages JavaScript, .NET, Python, Java SE only. Refer to this doc to know more about different supported SDK and its supported features in ACS.

You can send max of 100 emails/60 minutes or per one hour and these thresholds can be increased by raise a support & based on the different factors, business justification the upper limit will be increased by the backend team accordingly. Review this doc to know more sending limits in ACS Email Service.

Also, by enabling diagnostic setting and configure email events you can monitor the email status and delivery reports of the send email as well.

Hope this helps, let know if you have any further questions on this.

Thanks for the quick support.
I had some queries regrading your reply.
So for bulk email transaction, currently there is only azure communication services only or are there alternative service available. I am quite new to azure service.
My specific need was that I will send the list of recipients and the email template body via an API that is available in azure, and azure service will handle all other works such as queuing the emails, resending the email if it's undelivered, retry logic etc. such that my backend all need to worry about is just to call the API. The service also must provide a dashboard view to see the current status of emails and all.

I saw other options while browsing the internet such as Azure Communication Services (ACS) with Logic Apps, Event grid and send grid with azure.
which could exactly cater my need (very limited configuration is much acceptable)?

NAHID M A Thanks for your follow-up questions.

Yes, we have only ACS email service as mail server to send email to support end to end B2B or B2C scenarios.

Regarding the other question:

I understand that your application will send a sender email list and message body to an API it should fire the email to the sender list and also you want to monitor the status and retry it accordingly. if my understanding is correct.

To meet this requirement, you need to create a logic app using the ECS service Rest API to send, track the status of email as well.

Also, if you want to know more about the emails statistics in dashboard manner you can leverage the ACS insights by making use of Azure Monitor as discussed here.

Hope this helps, let me know if you have any further questions on this.

@VenkateshDodda-MSFT Thanks for the support
So using azure logic app we can create mechanism for resending the mail right.
Is there any guide regarding how to use azure logic app for specific email retry purposes?. And one more doubt was you mentioned about creating events to monitor the email in the first reply. There it's mentioned about creating event grid to work on events.
So which is the suitable mechanism for retry? Azure logic apps or event grid. The other query was that does email service support mail merge so that the we can replace the placeholders with the corresponding data of a particular user.
It would be also helpful if you can provide an estimated cost for increasing the quota of request limit and email recipients in each request.
The other thing to clarify is that, only by appending the email id's in to list of recipients in payload we can send bulk email or are there any other API's available for it?

If you are building your solution using logic apps in your workflow to trigger the Send Email Rest API action, you must monitor the status using the Get Send Email Result Rest API. By examining the "status" property and comparing it to a specific value, you can construct a retry mechanism that is appropriate for your needs.

By configuring email events using event grid, it will monitor a specific event. Once that event is triggered, you can use the payload of your event grid to trigger logic apps or function apps and build a retry mechanism based on it.

Please go through this documentation about the event grid email events.

It would be also helpful if you can provide an estimated cost for increasing the quota of request limit and email recipients in each request.

The cost will be varied based on the upper limit that has increased on ACS instance which you can further check with support team they would better person to share more insights on this.

Hope this helps, let me know if you have any further questions on this.

@VenkateshDodda-MSFT Thanks for the reply
Is it possible to perform mail merge via azure that is to replace the placeholder value in email body template with values of recipient address. Is that also possible through azure logic apps?

NAHID M A you want to make some part of the email body is constant for the all the recipients instead of recreating the whole body for every request you want to append only the dynamic values to body template dynamically.

If the above understand is correct yes this is achievable in logic apps.
