Mailosaur vs Litmus for email previews
Already using Litmus, or comparing your options?
Litmus offers a broad email marketing suite covering email previews alongside additional campaign testing, monitoring and optimisation tools.
Mailosaur gives teams a simpler way to access the email preview capabilities they need, backed by a platform built around email quality and testing.
If you want reliable email previews without paying for a much broader platform, Mailosaur could be the better fit.



See your email before your customers do
Email clients don't all render emails in the same way.
Something that looks great in one inbox can have broken spacing, images or layouts somewhere else.
Mailosaur Email Previews lets you check your email across different clients and devices from one place, so you can find problems before your customers do.
It's a faster way to make sure your emails look the way you intended, without the guesswork or manually checking multiple inboxes.
