Sending email with several base64 images

[Mattw112IG]

Hi I am trying to create an email with a lot of graphics which have been converted to base64.

The email with just the graphics worked fine.

Then I started adding in some dynamic fields pulling data from a SP list.

Now getting error

I'm assuming the dynamic data put me over the limit of 131,072? (Random number it seems).

Is there a way to configure this "maximum" or is it built in?

Is there another way to send this besides creating Azure App and all that with API v2.

Hi @Mattw112IG,

The expression evaluation limit is 131,072 characters, it's not a random number, 131,072 characters = 1,048,576 bytes = 1MB.

You could refer to the document to know the limits:

Limits and configuration - Power Automate | Microsoft Docs

It's unfortunate that there is no way could configure the "maximum", it's by design.

You could send the image link instead of send base64 code.

About that pleaser refer to this post, hope something could help you:

I ended up breaking the graphic up into pieces using a compose and then put the compose outputs into the email and it worked.

Thanks,
