5MB Maximum for Attachment File Size is extremely low

Please up your maximum file size for attachments (documents & photos). Currently you cannot upload a file larger than 5MB to attach to an email which is extremely inconvenient when you have well-designed trainings with multiple screenshots. Even after compressing my 13 page training it was 5.7MB, still too large. A simple Gmail account allows you to upload attachments that are up to 25MB, so only allowing for 5MB is very low. It's even more frustrating because our company is only using 9% of it's total available space, so there's plenty of room available for a couple larger attachments.


I had a file that was over 5mb and the Support Team Member tried to compress it for me but your system could not handle that size file.  If you could possibilty increase your systems ability to do larger files that would be great.

The 5MB limit is out of date. Many photos are 8-10MB fresh off the camera. Other programs let me upload these without having to resize them. Yours should too.


I totally agree.  I have ONE flyer that is apparently over the 5MB "limit" and now I cannot send it!!  What year is CC in?  Files are getting bigger people. 5MB by today's standards is nothing.  CC you need to get your act together and get with the times!  Really disappointed!!

I'm confused. Our newsletters usually contain 3 pages. saved as either  pdf or png files . . . with at least one graphic on each page. Size  of the those files has never been a problem until today. Although the first page  had only 664 kb (.664 MB) I still had to  reduce the size in order to load it into the  library. The second page also is less than 5MB, but I've spent the last 24 hours  trying to get the library to accept it. The loading  icon just keeps spinning. Is there some way to delete  that process and start over. . .and will that take care of the problem?

Could the total number of items in the  Library be the problem?


I used to be able to upload PDF files larger than 5MB and they were shrunk into ipegs before automatically.

Now that doesn't happen. This change took place 2 days ago. What's going on with that? 

I feel that 5 MB limit of upload file is pretty low. I am trying to send a compressed PDF file newsletter and unable to get it upload at below 5 MB limit otherwise the images would look terrible with blurry images if I had it compressed to below 5MB . I would suggest that we can increase to 10 or 15. The gmail allow us to send max of 20 MB, so why not Constant Contact?

We have been a long time Constant Contact customer and would like to see the document library max size limit increased past 5MB.  Most Email programs that are free allow 10, 20 or even 25MB of attachments.  Increasing the total size of the library does nothing as most of our newsletters start to creep into the 6, 7, 8MB range once pictures are added.  Reducing quality of the pictures, reduces the look and feel which is something we cannot compromise. 

Its ridiculous that pdf file size is limited to 5mb and should be larger(even 9-10mb would be reasonable).

Man! Here we are in 2020 and we are still struggling with CC file size. We need help with this, please! The 5 mb limitation is ancient. Please work on this! We enjoy all that CC has to offer, but you must develop something more user friendly. As we send out monthly newsletters, CC is our only mass media distributor who has this limitation. Thank you for listening, but keep us posted on your developments in this area.


CC Please increase attachment size. 5mb is extremely limiting!!!


It is time to raise the old 5 meg limit for uploads of documents.  Some of us need to share high resolution documents that can be printed in high resolution at the receiving end of our clients.  5 megs for a rich graphic filled bulletin/publication of many pages is too low.


Your 5MB max for upload to library is absurdly low.  It is 2020 with 5G connections, not 1996 with America Online and a modem.  I just started paying monthly with you to promote my ebook and I can’t even upload it. 

Sure, I can find a workaround to host it and I will.  But why am I paying you?

Real Estate

As a Realtor and real estate photographer, the fact that in order to upload images I have to resize every single one is very annoying.  I already shrink them way down for the MLS, to get them to 5mb they basically have to be thumb nails. The frustrations of this has lead me to the decision to switch.  Its taking me forever to get my photos in and its not worth it. 


I don't think my organization can continue using CC when 5MB is the max file size attachment. Considering now, you guys need to be more competitive .
