What's the standard email size for outlook?

[MPhipps]

Hi there,

I sent out our weekly mailer on Friday and noticed that when I opened it on Outlook (on mobile IOS), the email only dispayed half of the mailer. It only rendered half of the content on the email.  This is rather worrying and I am trying to avoid this happening again.

Do you know what the maximum size an email should be for it to render properly (and quickly) on Outlook?

Thanks,

Melanie

Hi @MPhipps ,

Each email client has its own set of guidelines, and each renders HTML and CSS in a different way. The standard size of an email should be 20MB on Outlook. It also depends on the version of the outlook you are using for example outlook for Office 365 supports emails upto 150MB, Outlook for iOS supports upto 64MB, whereas the outlook for android supports 10MB. You Search your outlook version and size limit on Google.

Hope this helps!

If we were able to answer your query, kindly help the community by marking it as a solution.

Thanks and Regards.

Hi there,

Thank you for your response, it has been the most helpful by far!  Do you know how I can check the size of my email template within Hubspot?

Thanks,

Hi @MPhipps,

We do not have an in-app solution to view an email size at the moment I'm afraid.

You could, however, try this workaround: send the email to yourself, then click on “Show original” to view the raw code, copy and paste it into a text editor and view the size of the resulting file. That should give you the size in KB.

I hope this helps!

Hi @MPhipps,

Thank you for reaching out to the Community! 

Just to clarify, does the email appear clipped (you see [Message clipped] View entire message at the bottom of your email) or is it just cut off? 

Most email clients have a size limitation in place, you can check Microsoft's limits here.

I would also recommend having a look at this Community post about email clipping.  

Cheers,
