Selling Security to People Who Distrust Email for a Living
Cybersecurity vendors face the hardest version of cold email there is. Your prospects — CISOs, security architects, SOC leads — are professionally paranoid, their inboxes sit behind the strictest email gateways in B2B, and they've been burned by every FUD-driven pitch in the category. Meanwhile, your SDR team runs a structured enterprise motion through Outreach: sequences, Salesforce-synced accounts, governance over who sends what.
What Outreach doesn't provide is the sending infrastructure itself. Each rep's mailbox is whatever you connect — and if that's your primary corporate domain, one aggressive quarter of outbound can land your product, support, and incident-response email in quarantine. This guide covers how cybersecurity teams pair ColdRelay infrastructure with Outreach: provisioning secondary domains and mailboxes, connecting them per rep, and structuring sequences that get past security teams' own filters.
Why Run Outreach on ColdRelay Infrastructure
Outreach is a sales engagement platform — it orchestrates sequences, tasks, and Salesforce sync, but it sends from whatever mailbox each rep connects. It doesn't provision domains, configure DNS, or manage the deliverability of the mailboxes themselves. For most industries that gap is a nuisance; for cybersecurity vendors it's existential, because the receiving side is Proofpoint, Mimecast, and Microsoft Defender for Office tuned to maximum suspicion.
ColdRelay fills the infrastructure layer. You provision dedicated mailboxes on isolated Azure tenants with dedicated IPs, with SPF, DKIM, and DMARC pre-configured — ready in about an hour. Security buyers check authentication headers more than any other audience; a missing DMARC record isn't just a deliverability problem, it's a credibility problem when you're selling to the team that enforces DMARC internally.
The pairing is additive, not competitive: ColdRelay is the infrastructure underneath, Outreach is the engagement layer on top. Your reps keep Outreach's sequences, governance controls, and Salesforce-first workflow — they just send from mailboxes built to land, on domains that can't take your corporate reputation down with them.

Provision rep-mapped mailboxes on ColdRelay
Pick secondary domains adjacent to your brand but separate from your primary corporate domain — the one your customers' security teams already trust for product and incident communications. ColdRelay supports 100-150 mailboxes per domain; most cybersecurity SDR teams provision 5-15 mailboxes per rep across 2-4 domains. Everything spins up on isolated Azure tenants with dedicated IPs in about an hour, with SPF, DKIM, and DMARC already configured.
Connect mailboxes as rep mailboxes in Outreach
In Outreach, each sending mailbox connects under Settings → Mailboxes for the rep who owns it. Connect each ColdRelay mailbox via its credentials so sends attribute to the right rep and sync back to Salesforce activity correctly. Admins can do this centrally through Outreach's admin console rather than asking each SDR to self-serve.
Set per-mailbox send limits to match the budget
In each Outreach mailbox's send-limit settings, cap daily sequenced emails at 2 per mailbox. That mirrors ColdRelay's per-mailbox budget — 4 sends/day total, split 2 outbound + 2 warmup — and keeps your volume profile below the thresholds enterprise gateways flag. ColdRelay's warmup runs continuously in the background, so there's no separate warmup period before reps can start sequencing.
Use governance profiles to lock the configuration
Outreach's admin governance controls let you enforce send windows, throttles, and sequence permissions by role. Lock send limits at the profile level so an eager SDR can't raise a mailbox to 50/day and burn a domain the whole pod shares. For security-buyer audiences, slow and authenticated beats fast and flagged, every time.
Build sequences and launch with Salesforce sync on
Create your sequences in Outreach with conservative step spacing — security buyers punish aggressive cadences. With sends flowing through ColdRelay mailboxes, every touch still logs to Salesforce through Outreach's native sync, so pipeline reporting and account ownership stay exactly as your RevOps team built them.
The Cybersecurity Outreach Playbook
Never send cold from the domain that signs your security advisories
Your primary domain carries the trust your customers' SOC teams extend to breach notifications and CVE advisories. Run every cold sequence from ColdRelay secondary domains so outbound reputation risk never touches the channel you'd need in an actual incident.
Kill the FUD — lead with the audit, not the apocalypse
CISOs delete fear-based pitches on sight; they've read better threat reports than your subject line. Structure Outreach sequences around something concrete and verifiable — a specific compliance deadline, a misconfiguration class you detect, a peer-company case study — and let the prospect draw the risk conclusion themselves.
Expect sandbox opens and link rewrites — measure replies, not opens
Security gateways detonate links in sandboxes and pre-fetch every email, so open and click data from this audience is noise. Configure your Outreach sequence metrics and reports around reply rate and meetings booked; deprioritize open-rate A/B tests that gateways have already corrupted.
Sequence by security function, not just title
A CISO, a SOC manager, and a GRC lead care about completely different sentences. Run separate Outreach sequences per security function with copy built for each, pulling from the same ColdRelay mailbox pool — capacity is shared across the pod, messaging is not.
Typical Cybersecurity Outbound Benchmarks (Outreach + ColdRelay)
| Metric | Benchmark | Notes |
|---|---|---|
| Inbox placement rate | 95%+ | Dedicated IPs, isolated tenants, and pre-configured SPF/DKIM/DMARC matter most against enterprise gateways |
| Reply rate | 1-2.5% | Security buyers reply less than any other B2B audience; tight ICP and non-FUD copy keep you at the top of that range |
| Outbound capacity per mailbox | 2/day | 4 sends/day total per mailbox — 2 outbound + 2 warmup |
| Time to first sequence | Same day | ~60 minutes to provision on ColdRelay, plus mailbox connection and sequence setup in Outreach |
| Reputation risk to corporate domain | Zero | Outbound runs entirely on separate ColdRelay domains — advisories, support, and incident comms stay untouched |
What It Costs: Outreach + ColdRelay
You pay per mailbox per month for the infrastructure, with volume tiers that drop as you scale (see the table below). Dedicated IPs, isolated Azure tenants, and pre-configured DNS are included.
Outreach is billed separately on its own per-seat enterprise subscription for sequences, governance, and Salesforce sync — priced per its current plans.
Infrastructure cost scales with mailbox count; Outreach cost scales with rep seats. The two stack cleanly — one bill for sending capacity, one for the engagement platform your SDR team already lives in.
| Mailboxes | ColdRelay price / mailbox / month |
|---|---|
| 1–199 | $1.00 |
| 200–999 | $0.85 |
| 1,000–4,999 | $0.70 |
| 5,000+ | $0.55 |
Each mailbox sends 4 emails per day — 2 outbound to prospects + 2 warmup. ColdRelay provisions mailboxes on isolated Azure tenants with dedicated IPs; Outreach handles the sending, sequencing, and inbox rotation on top.
Frequently Asked Questions
Does ColdRelay replace Outreach?
No — they sit at different layers and you use them together. Outreach is the sales engagement layer: sequences, tasks, governance, Salesforce sync. ColdRelay is the infrastructure layer underneath: the secondary domains, mailboxes, and dedicated IPs that Outreach sends from. Neither does the other's job.
Will cold outbound hurt the domain we use for security advisories and incident response?
Not when the sending mailboxes come from ColdRelay. Outbound runs on separate secondary domains, dedicated IPs, and isolated Azure tenants — completely walled off from the corporate domain your customers' security teams trust for advisories, support, and incident communications.
Do ColdRelay mailboxes need a warmup period before our SDRs can start sequencing in Outreach?
No separate warmup period. Warmup runs continuously as part of each mailbox's 4 sends/day budget — 2 outbound + 2 warmup — so mailboxes are ready to sequence from day one. Just set Outreach's per-mailbox send limits to 2/day and let ColdRelay handle the warmup side.
How many mailboxes does a cybersecurity SDR team need?
It depends on target volume. At 2 outbound sends/day per mailbox, a pod of 5 SDRs with 10 mailboxes each has 100 sends/day of capacity — appropriate for the low-volume, high-precision motion security buyers demand. ColdRelay supports 100-150 mailboxes per domain, so scaling the pool as pipeline targets grow doesn't mean scaling domain count linearly.
