Email Deliverability Repair Service
Google and Yahoo's 2024 bulk-sender authentication mandate created a durable, recurring compliance problem for small businesses that don't have in-house email infrastructure expertise — this productizes the fix as a flat audit plus an ongoing monitoring subscription.
Strong structural driver (a regulatory deadline most SMBs still haven't fully complied with) paired with genuine recurring-revenue potential from the monitoring subscription, but it requires real technical credibility to win trust, and the self-serve diagnostic tools you'd resell against (GlockApps, Mailgun Optimize) are cheap enough that a DIY-inclined customer can bypass you.
The regulatory trigger is well-documented and current: Google classifies any sender near 5,000 messages/day to personal Gmail accounts as a permanent 'bulk sender' subject to SPF+DKIM+aligned-DMARC and one-click-unsubscribe requirements, and enforcement was confirmed active into late 2025/2026 with non-compliant mail facing outright rejection. Mailgun's own survey data shows real gaps in compliance even among senders who knew about the rules, which points to an even larger population of small businesses that never heard about it and are simply watching open rates quietly decay. On the competitive side, the tooling layer (GlockApps Deliverability Suite from $49/mo, Mailgun Optimize from $49/mo, Postmark's free DMARC digests) is commoditized and self-serve — your value isn't the diagnostic, it's translating DNS jargon into a fixed problem for an owner who doesn't know what SPF even stands for, plus doing the actual DNS record changes they're afraid to touch themselves. That's a real service wedge, but it caps deal size unless you also sell ongoing monitoring, which is where the recurring revenue and defensibility actually live.
Demand spikes in Jan (post-holiday-email-blast owners noticing dropped open rates) and Sep-Nov as businesses fix deliverability ahead of Q4 email campaigns.
