    New trend alert! 🕺 You’ve already learned how to optimize dark mode, but can your emails be read in cosmic mode? From the bowling alleys and roller rinks, the cosmic trend has finally reached the inbox. Here are a few things to remember when designing your next email campaign: 🪩 Text should change color along with the pattern of the disco ball for optimal viewing. 🪩 Code snippets for dance floor integration are crucial for success in cosmic mode. 🪩 Your cosmic message still needs to be machine-readable! If not, the AI-generated summary will just be the lyrics to Stayin’ Alive, rather than your offer. The email industry is always changing! It’s only the first day of April!

In her latest blog post, Laura Christensen shares actionable tips to improve deliverability, keep subscribers engaged, and reduce frustration. No more subscribers tossing their computer in the trash! https://lnkd.in/eKkfnuXu

    One of our favorite Litmus Live sessions was when Danielle Gallant and Guy Hanson sat down with Al Iverson to discuss what’s coming next in the email space. There were so many fantastic questions in the live chat that our three experts didn’t have time to answer them all! Lucky for us, the three met up offline to unpack the remaining questions about DMARC requirement shifts, text-heavy email design, AI summaries, alternative email metrics, and more! https://bit.ly/4bsakMj
