> “Pierre and his team from Mailsoar have helped our company improve our email deliverability metrics to ensure that we get as many of our emails in our customers inbox as possible. Prior to his team working with us we saw a large number of emails going into spam, junk, or for the case of gmail, promotions/social. . As an online marketplace, emails are a crucial component to our supply and demand components interacting efficiently. This has helped improve that efficiency.”

They helped us set up a new dedicated subdomain to isolate our transactional/marketing mail flow from our primary domain, and worked with us to bring our DMARC compliance up to 97%. Since implementing MailSoar's recommendations, our email delivery rate has climbed to 99.6%. Just as importantly, the sender reputation for both humanx.co and mail.humanx.co went from "Bad" to "High". A great turnaround that's had a real impact on our ability to reliably reach our audience.”

## Frequently asked questions

What does an email deliverability consultant actually do?

An email deliverability consultant is a specialist who ensures your emails reach the inbox rather than the spam folder. At MailSoar, we diagnose why your emails land in spam or go undelivered, then fix the root causes — authentication (SPF, DKIM, DMARC), sender reputation, list hygiene, content, and infrastructure, so your campaigns consistently reach the inbox and drive measurable results.

How do I know if I need a deliverability expert?

If your open rates are dropping, emails are landing in spam or Promotions, Gmail or Outlook are throttling or blocking you, or you’re seeing bounces and blocklist warnings — those are clear signals. Not sure? Book a call with one of our experts, and we’ll tell you exactly where you stand.

How does MailSoar work with clients — audit, consulting, and ongoing support?

It depends on where you are. We run in-depth deliverability audits, provide hands-on consulting to fix and implement, and offer ongoing monitoring and optimization to keep you in the inbox long term. On an intro call, one of our experts will recommend the right approach for your situation.

What happens in the first meeting?

A relaxed 30-minute conversation with a senior deliverability expert. We’ll review your current situation, flag quick wins, and outline how we could help — no slides, no commitment. You’ll leave with clarity on your next steps, whether or not you work with us.
