Send Email Action attaching .bin file instead of expected attachment.

Hi,

Running into a weird issue where the Send Email action is attaching a .bin file instead of the expected CSV file. I attached a screenshot of the action & the .bin file in case either of those help.

Other email actions that attach a CSV file appear to be working so far, so it's just this one that is causing an issue oddly.

Please try removing quotes around file name and let us know the outcome. 

Unfortunately it ended up with the same .bin result.

Looking at it now

I have created a file similar to yours and it worked absolutely fine

One thing I've noticed that your bin file has this part Content-Type: application/octet-stream;

--v5wD6OCfRiEBZ9WfdaPl6nv=_epaKkRFZ9
Content-Type: application/octet-stream;
    name="3N2-ip.csv"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
    filename="3N2-ip.csv"
Content-ID: <3N2-ip.csv>

My message file looks like this

Content-Type: application/vnd.ms-excel;
    name="3N2-ip.csv"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
    filename="3N2-ip.csv"
Content-ID: <3N2-ip.csv>

Content type is calculated based on file extension

I do not know where did you get the file from but the csv file may not be actually csv because letter 'c' exists in many languages
I am just guessing here.

There are several characters represented by the letter 'C' in Unicode, including the basic Latin 'C' (both uppercase and lowercase), as well as various accented and modified forms of 'C'. In the Basic Latin block, U+0043 is the uppercase 'C' and U+0063 is the lowercase 'c'. Unicode also includes characters like 'Č' (U+010C) and 'ç' (U+00E7), which are 'C' with diacritical marks. 
Breakdown:

• Basic Latin:
  • U+0043: LATIN CAPITAL LETTER C 
  • U+0063: LATIN SMALL LETTER C 
• Other Unicode Blocks:
  • U+010C: LATIN CAPITAL LETTER C WITH CARON (Č) 
  • U+00E7: LATIN SMALL LETTER C WITH CEDILLA (ç) 
  • There are numerous other characters with 'C' as part of their representation in various Unicode blocks, such as Cyrillic, Greek, and phonetic extensions. 

Unicode encompasses a vast range of characters, and the letter 'C' appears in many different scripts and variations

Can you compress your file and email to us please?

Hi,

When you mention email, is there a specific address I should send to?

At first I thought it was the Contact Us form, but that doesn't allow attachments.
