You may know this already, but here's how you do 💌
Be aware that only sending a gif can land in the spam folder.
Here are some tips to have in mind.
High image to text ratio. If your email contains mostly images, that's a red flag for spam scorers. They can't analyze images properly, so they don't like them.
So include a text version of your email as well.
High link to text ratio. It's the same as we mentioned above. Avoid to many links and have more text in your email.
Full URLs or URL shorteners. Full URLs (ie https://vaam.io/share/12345) will increase your spam score. Spammers are lazy and often don't bother to make proper links. So a "See my vaam" with an attached link will perform better than the full URL.
