Sounds familiar?

Your emails are landing in spam. Inbox placement is declining. Bounce rates are rising. Your sender reputation is suffering. You may be facing blacklisting, authentication, or other deliverability issues. The symptoms may look similar, but the underlying cause can be very different. You need to know what’s really going wrong.

Get a call back

Delivered is not the same as inboxed.

Your ESP reports a 99% delivery rate, but that only means the receiving server accepted your emails. It doesn’t tell you whether they reached the inbox or spam.

“We partnered with MailSoar to improve our email deliverability and sender reputation. 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.”

Questions
we get asked

What does an email deliverability consultant actually do?

A deliverability consultant identifies why your emails are being blocked, filtered, or sent to spam, then implements the changes needed to improve inbox placement. This can include authentication and DNS, sending domain and IP architecture, blacklist issues, sending practices, list segmentation, engagement strategy, and ongoing placement monitoring.

Our approach is operational, not just advisory: we implement the work directly inside your existing stack.

How long does it take to improve email deliverability?

Some authentication and configuration issues can be fixed within days. Reputation recovery typically takes 2 to 6 weeks, as mailbox providers need to see consistent, healthy sending before inbox placement improves.

The timeline depends on the root cause, your sending volume, and the severity of the issue.

Do we need to change our ESP?

Usually, no. Our consultants work across the major ESPs and CRMs, and we implement changes directly within the stack you already use.

In most cases, the platform itself isn’t the problem. Configuration, infrastructure, reputation, or sending practices are.

Why are my emails going to spam?

Spam placement usually comes from one of four areas: authentication (SPF, DKIM, DMARC) that is missing or misaligned, a damaged domain or IP reputation, sending practices that trigger filters (volume spikes, inactive contacts, high complaint rates), or content and links that look risky to mailbox providers.

The symptoms look alike, which is why we start with a diagnosis rather than a checklist.

Can you get our domain or IP removed from a blacklist?

Yes. We identify which lists you are on and whether they actually affect your delivery, fix the cause that got you listed, and handle the delisting requests for you. Delisting without fixing the cause rarely lasts, so both are part of the work.

Which ESPs do you work with?

We work inside your existing platform, including Braze, Klaviyo, Salesforce Marketing Cloud, HubSpot, Brevo and most other major ESPs and in-house MTAs. You do not need to switch tools to improve deliverability.

Do you handle IP and domain warm-up?

Yes. We build a staged warm-up plan based on your volumes, audiences and mailbox providers, then adjust it day by day based on placement and engagement data. This applies to new IPs, new domains and ESP migrations.

How do you measure inbox placement improvements?

We combine seed-list placement tests, mailbox provider data such as Google Postmaster Tools and Microsoft SNDS, and your own campaign metrics. You get a baseline at the start and regular reporting on how placement and engagement evolve.

Can you help us meet Gmail, Yahoo and Microsoft sender requirements?

Yes. We audit your setup against current bulk sender rules (authentication, DMARC policy, one-click unsubscribe, complaint rate thresholds) and implement what is missing so your emails stay compliant as the requirements change.

What do you need from us to get started?

A 30-minute call to understand your situation, then read access to your ESP and DNS, and your recent sending data. We take it from there and tell you exactly what we need from your team, if anything.

What does it cost?

Every email infrastructure is different. Pricing depends on factors such as sending volume, domains, email streams, and the level of support required.

We’ll assess your setup, identify what’s impacting deliverability, and define the right next steps for your business.

You’ll receive a tailored scope and proposal within 48 hours of your first call—with no cost and no obligation.
