Monthly retainer
A dedicated deliverability engineer reviews your metrics, blacklist status, and inbox placement trends every month. We catch problems before they become crises.
Best for: High-volume senders (1M+ emails/month)
Migration Support
4–8 weeks
Switching ESPs, domains, or IP pools is the most dangerous moment for deliverability. We plan it, manage the warmup, and monitor reputation through the transition.

The full diagnostic
SPF, DKIM, DMARC alignment
We verify all three protocols are configured, aligned, and enforcing. Most companies have SPF but miss DKIM rotation or have DMARC stuck on p=none.
Content and sending patterns
Subject line triggers, HTML weight, link domains, sending frequency, and segmentation strategy — all reviewed against deliverability best practices.
IP and domain reputation
We pull data from Google Postmaster Tools, Microsoft SNDS, SenderScore, and every major blacklist to build a reputation profile.
ESP configuration
Dedicated vs shared IPs, warmup status, suppression list management, feedback loop enrollment, and bounce handling settings.
List hygiene and trap exposure
We analyze your bounce patterns, identify likely spam trap hits, and audit your list acquisition sources for risk.
Compliance and readiness
CAN-SPAM, GDPR consent records, Google/Yahoo bulk sender requirements, one-click unsubscribe, and BIMI readiness.
Not promises. Measurements.

Before you book
How is this different from using VeriFox tools?
Our tools handle verification, scoring, warmup, and monitoring automatically. Consulting is for complex problems that need human expertise — persistent blacklistings, infrastructure migrations, or deliverability that has degraded without a clear cause.
Do I need to be a VeriFox customer?
No. Consulting is standalone. We work with clients regardless of which tools they use. That said, most clients adopt our tools after seeing what proper list hygiene does.
Can you help with a specific ESP?
Yes. Deep experience with SendGrid, Mailgun, Amazon SES, Postmark, SparkPost, Klaviyo, HubSpot, ActiveCampaign, Mailchimp, and most enterprise platforms.
30-minute discovery call. Free. We will tell you whether
consulting is the right fit — or if our tools are enough.
