Importing files larger then 5mb

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.

Updating the status of this request to Under Consideration to support our new community idea statuses to add better insight into your feedback.


We acknowledge that this particular feedback has been requested for quite awhile. The current file size requirements can be quite limiting for some. We currently have some tickets open within our product and engineering teams to look at increasing file upload sizes. At this time, there are no further updates in terms of expected timelines. We'll keep you posted.

I upload our member bulletin each week. Suddenly it will not take files over 5 meg - I tried a 5.3 meg file and it would give a non-discript "try again later" error message when I tried to overwrite the existing file. I tried a direct upload (no replacement) and got a mouse-over error message saying that you can't upload images over 5 meg - its not an image its a pdf. Is it broken or is this something new?
I have uploaded a 8, 9, and 10 MB pdf to CC in the past to send to customers. Now CC is calling my pdf an image and will not allow me to upload it saying it must be no more than 5mb....really? It's only 7 megs and I need to get it out ASAP!!!

I am sorry to hear this is happening. There is a max file size of 20k lines in your upload currently. Are you importing over 20k lines or could the error be caused by something else?

Hello, I'm not sure what you're referring to. Could you please provide me with some more information? Thank you!

If the storage capacity is large enough to tolerate files exceeding 5M, then why is there a cap?

My contact file is 1.322Mb. So now I have to go in and split the file and upload twice in order to make this work? Back in the early days of ConstantContact this was true too but that problem was overcome a few years ago and I used to be able to upload our entire db all at once. Sad the technology is going backwards. Please fix. Thanks. Darius.

Thank you for providing your feedback!


What kind of issues are you experiencing?  Did you receive an error message when uploading your contacts?


With the new contact system you can still upload a single spreadsheet of contacts as long as you want them to go in the same list/lists.  Please feel free to reach back out to us and we would be happy to walk you through this process.

Paring back Excel uploads to 1MB is not an upgrade, Constant Contact. Not impressed.

Hi Charles,


I'm sorry to hear this. Unfortunately. our filed upload limits have not changed. They remain at 1 mb or 20,000 contacts. I took a look at your account, it looks like you uploaded 2 files yesterday totalling roughly 11,000 contacts. This is an unsually low number for it to reject, if this is the file you are referring to. You can try re-saving the file as a .csv. If there is any formatting causing a large file size, this should clear it out and allow you to upload as one.


I sent an email to your inbox to the address that we have on file. I would be more than happy to take a look at the file if you could reply back with the information from that email.

Contact management process is more difficult and lengthy with the recent upgrade. Limit of 1 MB in uploads is too low and causes us to do much more work.

I am sorry you've been bumping against that upload limit! What you may find helpful is to save your spreadsheet as a .csv file type and try uploading that way instead of splitting what you have. Changing to this file type might make for a smaller file and allow for fewer steps in the long run. If you continue to see issues with it, I'd recommend you contact the support team here for further assistance. We can be reached at 855-229-5506 when you have a moment!

The new 1 MB excel file size limit is not user friendly and should be removed. Previously we could export a fresh list of members from our member database and easily upload. Now there is a multistep process to split the lists. _Please fix the file upload page.
when i signed up for constant contact the file size limit for pdf uploads was 10mb. it was downgraded to 5mb without any price adjustments. my primary use of constant contact is to email electronic publications to customers and the 5mb limit is below my needs. it's unfortunate since I really liked constant contacts other services.
