Deliverability Consulting That Finds the Cause.

Six layers: email authentication (SPF, DKIM, DMARC), IP and domain reputation, list hygiene and spam-trap exposure, content and sending patterns, ESP and infrastructure configuration, and compliance. You get a written report with every finding ranked by impact, a live walkthrough, implementation support, and 30 days of post-fix monitoring. Continuous coverage afterwards can run on the DMARC monitor and our other automated tools.

Engagements are scoped on the free 30-minute discovery call and priced by sending volume and complexity, quoted in your local currency. No long-term contract. If your problem turns out to be list quality, we will say so on the call: pay-as-you-go verification credits never expire and cost far less than a consulting engagement.

72 hours is the typical resolution once the root cause is fixed, though every blocklist runs its own delisting process and some major filters update on their own schedule. Delisting without fixing the cause just gets you relisted, so we fix first and file second. Afterwards, automated blacklist monitoring watches the major lists and alerts you on the first hit.

Tools handle the automatable layers: email verification cleans your list, email warmup builds sender reputation, monitoring catches drift. Consulting is for problems that survive all of that: persistent spam placement with clean metrics, reputation damage with no obvious trigger, or a migration where one mistake costs weeks. The discovery call exists to tell you honestly which one you need.

Yes. The rules for senders above 5,000 messages a day are concrete: aligned SPF and DKIM, a published DMARC policy, one-click unsubscribe honored within two days, and spam complaints kept under Google's 0.3% threshold. Every audit includes a compliance pass against the current requirements, and 100% of our engagements over the last 12 months reached full compliance.

It depends on volume and consistency. At lower volumes, a well-managed shared pool usually outperforms a dedicated IP you cannot keep warm; at sustained high volume, dedicated gives you a reputation you fully control. The audit answers this with your own data, and an email server test shows how your current setup presents to receiving servers before you commit either way.

No, and you should walk away from anyone who does. Mailbox providers do not sell guarantees, and filtering changes weekly. What we commit to is measurement: a baseline inbox placement test before any changes, the same test after every fix, and a written record of what moved. Across recent engagements, the average inbox rate improvement is 42%.

Yes, with conditions. Lists must be verified before sending, since cold lists carry the highest catch-all and spam-trap risk. We will also insist on separate sending domains and a proper warmup ramp before volume. What we will not do is help anyone send to people who never asked to hear from them at scale.

Read-only access to your ESP dashboard, DNS records, Google Postmaster Tools, and recent campaign reports. Nothing changes on your side until you make the changes yourself, with us on the call. Verifox is SOC 2 Type II audited, and any addresses we verify during an engagement are processed in memory, never stored, logged, or sold.

No. Consulting is standalone, and we work alongside whatever stack you run: SendGrid, Mailgun, Amazon SES, Postmark, Klaviyo, HubSpot, ActiveCampaign, and most enterprise platforms. Many clients later wire our verification engine into signup and import flows because it removes the list-quality class of problems permanently; the API reference shows the full integration surface.
