Hi,
Does someone know what the size of the header image must be?
Please let me know.
Typically the rule of thumb for emails is that images should be no wider than 600px but with more clients supporting responsive design you can push these limits at times, but the key is just reviewing stats on your emails to see what clients/devices are being used and let the data guide what you do.
Here’s a recent article from Campaign Monitor on the subject that explains this in a bit more detail: Best Image Width & Sizes For Email Campaigns | Campaign Monitor
Yes thank you. I’ll ask a hubspot partner to develop a template for our company
With kind regards,
Maaike
