email deliverability

Definition

The likelihood that your carefully crafted email actually reaches the inbox instead of being banished to spam purgatory by overzealous filters. It's a constant battle against algorithms that assume all marketing emails are basically viruses in disguise.

Example Usage

Our email deliverability dropped to 60% after we used the word 'free' seventeen times and added eight exclamation points.

Origin

Email marketing challenge that emerged in the early 2000s as spam filters became more sophisticated

Fun Fact

The average email deliverability rate is around 85%, meaning 15% of your list never even gets the chance to ignore your message.
