Cold email in 2026 is unforgiving. Gmail and Microsoft both started enforcing DMARC for senders over 5,000 messages/day in early 2024. Domain reputation moves fast. Get the infrastructure wrong and your cold email lands in spam — quietly, irreversibly, until you replace the domains.
Rev Growth's B2B email outreach service is built so you never have to think about deliverability infrastructure. We handle the domains, the warmup, the authentication, the volume management, and the content patterns that keep you in the inbox.
What's included in our B2B email outreach service
Warmed sending infrastructure
Three Google Workspace mailboxes on dedicated sending domains, warmed for 21 days before any cold sends. SPF, DKIM, DMARC fully configured. Domain reputation monitored continuously via Google Postmaster Tools and inbox-placement testing.
Plain-text sequences
5–14 emails over ~21 days, written in plain text — no HTML formatting, no images, no tracking pixels. Reads like a human between meetings, not a marketing campaign. That's the format that gets through 2026 spam filters cleanly.
Per-recipient personalization
Not just merge-tag swap-outs. Real per-prospect openers built from their actual job posting, recent activity, or the specific signal that surfaced them as a target. Generic-tone AI personalization is dead in 2026 — we go deeper.
Variable cadences
5 emails for warm segments, 12–14 for harder targets. We tune cadence length per segment based on what's actually replying.
Why most B2B email programs fail
Three patterns destroy reply rates: heavy HTML formatting that triggers marketing-content filters, sending past the daily mailbox cap (which decays reputation), and generic AI personalization that prospects pattern-match in two seconds.
We avoid all three by design. The result: reply rates 3–5x the typical agency average, on send volumes that the inbox treats as a real human writing real emails.
