Email deliverability is the ability to deliver emails to recipients' inboxes.
Spammy words & phrases can hurt your email deliverability.
That is why we've created Autoklose Template Analyzer or simply Spam Analyzer.
Part of that feature is to highlight spammy words while you are writing.
The idea is that you change/replace those highlighted words/phrases with more suitable ones that would increase the likelihood of your emails being delivered to your prospects' inboxes.
