We are currently designing our emails in Adobe Illustrator, we are looking for a plug in, extension or some kind of quick preview to check graphics viability in dark mode. Does anyone know a tool to help us do this? Thank you in advance
Why are you designing emails in Illustrator?
You need to be using an email platform like Mail Chimp, Send in Blue - etc.
A lot have all the tools you need and can be absolutely free to send when under a certain number.
