Why is this
important
Avoid cut-off in mobile
Over 75% of emails are opened on mobile devices. Smaller screens, less space. Make sure your message is fully visible.
Improve deliverability
Higher open rates send the right signals to Inbox providers, telling them their users want to hear from you, which keeps you in the Inbox.
Drive higher engagement
Every session counts. More opens bring more clicks, more clicks bring more conversions.
Plan A/B tests properly
Testing wrong variants is equal to not testing at all. Make sure your tests lead toward improvement.
