What Is Deliverability?


It's simple, deliverability is your domains ability to send emails that end up in the main/primary inbox, which is exactly where your want them. Otherwise they are filtered into the 'spam' or 'promotions' folder where they will not be opened or trusted, this, in turn, hurts deliverability even more.
The reason for this filtering is as a result of increased spam prevention measures implemented by major email providers like Gmail, Microsoft Exchange, Yahoo etc. due to them trying to improve the user experience and market over-saturation.
So, deliverability is a sort of score given to your domain based on its reputation.

Biggest Change for 2025
You can’t go from zero to blasting 100K+ contacts without warm-up.
Example warm-up cadence:
Start with 500 contacts.
Then 1K → 5K → 10K → 25K, etc.
Expand only if you're getting good open rates.
Even large lists (e.g. 1M+) can be warmed over 1–2 months.

There will be an initial drop in revenue from email at the early stages of warm-up but a warmed email address will more than make up for it.
