Mitigate Outbound Risk

While cold emails are the foundation of every B2B sales team’s go-to-market, they create the highest risk to your deliverability and email infrastructure.

Frequently Asked Questions

What new Gmail/Yahoo sender rules mean for outbound — and how should a platform help?

They raise the bar on authentication and complaint control, so reputation protection is now the priority. They now require bulk senders to authenticate mail (SPF and DKIM), publish DMARC, keep user-reported spam below 0.3%, support one-click unsubscribe (and honor it within two days), and maintain sane DNS/TLS. Your platform should monitor SPF/DKIM/DMARC continuously, enforce one-click headers, track complaint rate and auto-pause cohorts near 0.3%, and block risky sends by scoring catch-alls, traps, and likely complainers before cadences run. It should also test content for filtering and surface inbox placement by domain/subdomain.

Do seed lists reflect real corporate filtering or should we test with real B2B inboxes?

Seed lists rarely mirror corporate filtering. They’re static addresses that are often whitelisted, sit outside enterprise gateways, and generate no user engagement, so they overstate inboxing and miss foldering differences. Testing across real B2B inboxes shows true primary vs. spam/promotions placement by domain, captures gateway effects (e.g., Proofpoint, Mimecast, M365), and validates content and sender settings before launch. Allegrow measures placement on live corporate mailboxes and rolls results up per domain\ so you can act early.

Which early-warning metrics should we track and what thresholds trigger action?

The main tripwire is the user-reported spam rate. When it approaches 0.3% (about 3 complaints per 1,000 emails), Gmail/Yahoo bulk-sender rules begin pushing mail to spam. Set an internal alert at ~0.2% and pause the cohort at 0.3% while you fix list risk and copy. As secondary guardrails, keep hard bounces under 2% and investigate sharp drops in primary-inbox share or spikes in spam-folder share.
