A product update should be sent once a month with updates about what you shipped recently. This typically includes new features, improvements, and bug fixes.Things to keep in mind:
Brevity is key. Users don’t want to read a novel.
If you send valuable content, users will come to expect (and open) it.
It’s okay to send multiple emails in a month if that’s your shipping cadence.
Add a simple subject line, like “The latest updates from Loops”
Add a simple intro paragraph, with a link to the full changelog, potentially socials and a highlight of the most important changes along with a call to action to read the full email.
Try to limit the number of updates to 2-3, and make sure they are relevant to the content. It’s better to have a single or a couple impactful, relevant updates than a long list of updates that are not relevant to the user.
In the footer, add a link to the full changelog, socials, and a link to unsubscribe.
