Tell us what is failing
The problem is usually bigger than one DNS record when several symptoms appear together or previous fixes have not changed placement.
Messages authenticate but still miss the inbox, placement varies by provider, or performance declined after a migration, campaign or volume change.
Why email goes to spam or the junk folder →SPF, DKIM and DMARC exist, yet alignment, duplicate senders, forwarding, third-party tools or return-path configuration create hidden failures.
Bounces, deferrals, complaints, blocks or weak engagement are increasing and you need evidence that separates reputation from infrastructure.
The deliverability issues we inspect, isolate, and resolve once we know what is blocking inbox placement.
Audit and repair your authentication records to prove to email providers that you're a legitimate sender.
Open the authentication troubleshooting guide →Check if your domain or IP is blacklisted and handle the removal process with major blacklist providers.
Assess and recover your sender reputation with provider evidence, controlled remediation and monitored sending.
Open the sender reputation recovery guide →Test exactly where your emails land across Gmail, Outlook, Yahoo and more — before you hit send.
Fix sending settings in Mailchimp, ActiveCampaign, HubSpot, SendGrid, and other platforms.
Plan a safe sending warmup for new domains or IPs to build reputation without triggering spam filters.
A focused diagnosis is useful for one obvious symptom. A full audit examines the complete sending environment and produces written findings, risk priorities and a remediation roadmap your team can act on. Basic Audit $180 per domain; Full Audit $399 per domain, adding blocklist checks and spam placement reporting.
A remediation process: confirm the cause, agree the changes, make them, and verify what moved.
Tell us your domain, sending platform and symptoms. For a single clear symptom we confirm the cause directly; where several systems send from one domain, a full deliverability audit establishes it first. Initial review commonly begins within 24–48 hours once the required information is available.
We set out what will be changed, in what order, what carries risk and what should be left alone. Nothing is altered on your domain or platforms without your approval.
We handle the agreed DNS, authentication, platform and sending-configuration work directly, or guide your team through it where you would rather keep the changes in-house.
We re-test the authentication results, provider signals and placement evidence we can measure, then hand you a written record of every change and its prior state.
Work done and verified, scaled to the issue instead of a one-size-fits-all package.
Hands-on DNS, authentication, platform and sending-configuration changes, carried out on your approval—or handed to your team to apply if you would rather make them yourselves.
Authentication results, provider signals and inbox placement re-tested after the change, with the limits of that evidence stated rather than dressed up as a guarantee.
What was altered, what it was before, and what to watch afterwards—so your team can maintain it and revoke our access cleanly when the work is done.
An email deliverability audit is a bounded, paid investigation of the whole sending environment—authentication, reputation evidence, infrastructure and sending behaviour—that ends in written findings and a prioritised roadmap rather than repairs. It is the better starting point in two situations: you already know you want a full audit documented for your team, or you have already spent money on tools, fixes or a previous consultant and placement still has not improved. Where earlier changes have not worked, establishing which signal is actually failing costs less than another round of repairs aimed at the wrong cause.

Platforms we investigate: Google Workspace, Microsoft 365, HubSpot, Mailchimp, ActiveCampaign, Klaviyo, SendGrid, Mailgun, Amazon SES and other SMTP or API-based systems. When several tools send from one domain, we assess them as one connected reputation environment. For campaign planning, journeys and reporting beyond deliverability, see our email marketing service.
The same email deliverability principles, applied to the platform the mail actually leaves from.
Email deliverability work on Microsoft 365 covers connector configuration, tenant-level policy and the authentication records that Exchange Online requires.
Email deliverability on Google Workspace focuses on SPF include limits, DKIM key rotation and the routing rules that quietly override placement.
Email deliverability for Klaviyo, Mailchimp, Brevo and similar platforms, where a shared sending pool means reputation is partly inherited.
Email deliverability for application mail through SendGrid, Postmark, SES or a relay, where receipts and resets must not share an identity with marketing.
We work from a named, least-privilege account you create for us, we require multi-factor authentication on anything we touch, we capture the prior state before every change, and we hand you a written revocation checklist when the work is done. One legal entity — Yeevu LLC — provides the service, receives payment and carries the liability.
Trust & Security →Relevant examples only: authentication, migration and sending-environment repairs rather than a mixed website portfolio.
Connected the rebranded domain to Google Workspace and Wix, then authenticated both day-to-day and marketing mail with aligned SPF, DKIM and DMARC while retaining an enforcing DMARC policy.
Scope: DNS alignment, multi-platform authentication and DMARC enforcementInvestigated a wider technical failure spanning email migration, DNS and CRM automation, then repaired the sending environment as part of a four-project engagement.
Scope: email migration, deliverability remediation and connected-system repairResolved DNS, SPF, DKIM and DMARC misconfigurations affecting email and connected automations during a repeat multi-project engagement.
Scope: DNS diagnosis, authentication repair and verificationWhat specialist help can and cannot do, when an audit is useful and how an engagement starts.
Email deliverability work is scoped against the number of sending domains, the platforms involved and whether reputation repair is needed. Scope and price are confirmed in writing before access is requested.
An email deliverability consultant investigates why legitimate messages are blocked, rejected or routed to spam. That can include authentication, DNS alignment, sender reputation, sending infrastructure, list practices, message patterns and provider-specific evidence. The result should be a prioritised remediation plan, not a generic checklist.
No credible provider can guarantee inbox placement because Gmail, Microsoft, Yahoo and other mailbox providers make their own filtering decisions. We identify controllable causes, implement or recommend evidence-based fixes and verify the resulting signals without promising an outcome no consultant controls.
No. YeevuFix works with business mail, transactional systems, newsletters, CRM campaigns and legitimate outbound programmes. The diagnostic approach changes with the mail type, sending platform, audience and symptoms.
A quick diagnosis is suitable when you need an initial direction or have one clear symptom. A full audit is better when the cause is unclear, several systems send on the domain, performance has declined over time or your team needs a written, prioritised remediation plan.
We investigate Google Workspace, Microsoft 365, HubSpot, Mailchimp, ActiveCampaign, Klaviyo, SendGrid, Mailgun, Amazon SES and other SMTP or API-based sending systems. Multi-platform domains are reviewed as one reputation and authentication environment.
Initial review commonly begins within 24 to 48 hours after we receive the domain, symptoms, sending-platform details and required access. Complex reputation or multi-platform cases can require a longer observation window, which we explain before work begins.
"What I was unable to fix for six, long months, Yeevu was able to fix in less than twenty minutes."
"Yeevu was absolutely brilliant and did everything I needed in super quick time. I will definitely use again."
Tell us what is happening, which platforms send from the domain and what you have already tried. We will tell you whether the next step is a focused diagnosis, a full audit or a specific repair.
