Email Deliverability Stats

How It Works

Our email deliverability consultants help you optimize your email deliverability rate and boost your sending reputation in just three steps:

Understand & Audit

Our team will review your existing email marketing strategy. We'll look at the current state of your email campaign, including how you segment your audience, what type of content you're sending, and how frequently you're sending emails. We'll also look at the performance of each campaign, including open rates and click-through rates.

Identify & Execute

Our email deliverability expert uses the gathered information to identify issues in your account that may be causing problems with email delivery and then lets you fix them quickly. It helps you avoid unnecessary delays or blocks by ISPs and improves your sending reputation with them (and thus helps prevent any future delays).

Remediate & Monitor

Our email deliverability consultant constantly monitors how well your emails are delivered, so you can respond quickly if any issues arise. It uses data from over a million unique users every month, so we know precisely how most ISPs treat different messages (eCommerce, marketing, loyalty programs).

Are your emails always bouncing back? Remove those email addresses that bounce your emails back immediately. If you keep sending emails to them, your email address would be blacklisted.

The size of your email can have an impact on email deliverability, but its impact is much lower than engagement and list-health practices.
