to waste. Currently, one in every seven messages sent
worldwide fails to land in the inbox, a number that can vary
greatly by industry, country, and inbox1
. Email marketers
are increasingly citing deliverability as one of their main
barriers to effective marketing. From 2018 to 2019, it has
surged by over 12%, with 37% of marketers citing it as a
top concern2
.
There’s no point spending time crafting great content if
your messages never reach your subscribers’ eyes. In this
Deliverability 101 guide, we’ll help you start off on the right
foot and land your email to its intended destination. We’ll
also explore how to keep your subscriber engagement at
the heart of your email strategy.
Fasten your seatbelts! We’ve got a bit of ground to cover
before reaching destination success - but don’t worry,
you’ll enjoy the ride.
