Is there any way to stop getting the proofing error for "too much text"? I use Emma to send newsletters that occasionally are quite long. It's frustrating to be stopped while trying to send for this no really an "error".
The Proofer tool works on the basis of best email practices and is just a guide to maximize the deliverability of your mailings. After all, we want to ensure that your email has the best chance of reaching your reader's inbox! Although we aren't able to disable it, it's totally fine to ignore it and click "Send anyway" if your certain there are no actual errors in your mailing :)
We always recommend sending out a test to make sure your mailing looks as expected -- if everything is in place then you'll be good to go!
