Healthtech Outbound, Run Through Apollo
Healthtech outbound has a shape of its own. You're not emailing clinicians about patients — you're emailing practice administrators, office managers, and health-system IT and ops leaders about software that runs their business. The buyers are compliance-conscious, the procurement cycles run through committees, and a single deliverability mistake on your primary domain can stall every deal in your pipeline.
Apollo is where the targeting and sequencing happen: its database filters by healthcare specialty, title, and practice size, and its sequences mix email and call steps for gatekeeper-heavy markets. ColdRelay is the infrastructure underneath — the secondary domains, mailboxes, and dedicated IPs Apollo actually sends from. This guide covers how healthtech teams wire the two together and run specialty-segmented outbound that books demos with the people who sign practice-level contracts.
Why Run Apollo on ColdRelay Infrastructure
Apollo gives you the data layer and the sending engine: a contact database you can slice by healthcare specialty and title, saved personas for your repeatable ICPs, and sequences that send from whatever mailboxes you link. What it doesn't do is provision those mailboxes or own their deliverability — that's the infrastructure layer's job.
That's where ColdRelay fits. You order dedicated mailboxes on isolated Azure tenants with dedicated IPs, fully DNS-configured (SPF, DKIM, DMARC) and ready in about an hour, then link them in Apollo and start sending — no warmup waiting period, because warmup runs continuously as part of each mailbox's daily budget.
For healthtech specifically, the separation matters twice over. First, your primary domain carries your HIPAA-conscious brand — the one prospects will scrutinize during security review — and it should never touch cold volume. Second, one important boundary: your prospecting data is strictly business contact information (names, titles, practice addresses, work emails). No patient data ever enters the outbound stack, which keeps your cold email program cleanly outside PHI territory — a point worth stating early to compliance-minded buyers. The pairing is additive, not competitive: ColdRelay is the infrastructure, Apollo is the data and sequencing layer on top.

Provision mailboxes on ColdRelay
Pick secondary domains adjacent to your healthtech brand — never the primary domain your security questionnaires and BAAs reference. ColdRelay supports 100-150 mailboxes per domain; most healthtech teams start with 50-150 mailboxes across 1-3 domains. Everything provisions on isolated Azure tenants with dedicated IPs in about an hour, with SPF, DKIM, and DMARC already configured.
Link the mailboxes in Apollo
In Apollo, go to Settings → Mailboxes and add each ColdRelay mailbox as a linked mailbox. Set the per-mailbox daily sending limit to 2 outbound emails per day — that mirrors ColdRelay's budget of 4 sends/day total per mailbox, split 2 outbound + 2 warmup. Warmup stays on ColdRelay's side; Apollo only handles the outbound sends.
Build specialty-segmented lists with Apollo filters
Use Apollo's database filters to slice the healthcare market by specialty (dental, dermatology, behavioral health, ortho), title (practice administrator, office manager, director of IT/operations), and practice size (number of employees or locations). Save each combination as a persona so list-building is repeatable as you expand into new specialties. Keep every list strictly business-contact — work emails and practice addresses only, never anything resembling patient data.
Create sequences with email and call steps
Build an Apollo sequence per specialty segment, mixing automated email steps with manual call tasks — in practice-based healthcare, the phone is how you get past the front desk after an email opens the door. Lead the first email with what you do and your compliance posture (HIPAA-ready, SOC 2 if you have it), because that's the first filter a practice administrator applies.
Attach mailboxes, launch, and scale
Assign your linked ColdRelay mailboxes to each sequence and let Apollo rotate sends across them. With 50 mailboxes you have 100 outbound sends/day of capacity; with 150, 300/day. When a new specialty segment proves out, scale mailboxes on ColdRelay rather than pushing existing ones past their per-mailbox limits.
The Healthtech Apollo Playbook
Sell to the administrator, not the clinician
Target Apollo personas at practice administrators, office managers, and health-system IT/ops leaders — the people who own scheduling, billing, and vendor decisions. Clinical outreach is a different discipline with different rules; keep your cold program on the business side of the practice, with strictly business-contact data.
State your compliance posture in the first email
Healthcare buyers screen vendors on compliance before they read the pitch. A single early line — HIPAA-ready, BAA available, SOC 2 — answers the question they're already asking and earns the rest of the email a read. Burying it until the demo costs you replies.
Segment sequences by specialty, not just title
A dental practice, a dermatology group, and a behavioral health clinic run on different software, workflows, and pain points. Use Apollo's specialty and keyword filters to run separate sequences per vertical so the copy can reference the actual systems and bottlenecks each one lives with. Generic 'healthcare' copy reads like spam to all of them.
Sequence for the committee, not the click
Practice and health-system purchases go through committees — the administrator who replies rarely signs alone. Structure your CTA around a short intro call they can bring to their ops or IT counterpart, and expect the cycle to run weeks to months. The win condition for cold email here is getting onto the evaluation shortlist, not closing from the thread.
Typical Healthtech Outbound Benchmarks (Apollo + ColdRelay)
| Metric | Benchmark | Notes |
|---|---|---|
| Inbox placement rate | 95%+ | Dedicated IPs and isolated tenants matter in a market where practice inboxes filter aggressively |
| Reply rate | 1.5-4% | Gatekeeper-heavy market; compliance-forward copy and tight specialty segmentation drive the top of the range |
| Outbound capacity per mailbox | 2/day | 4 sends/day total per mailbox — 2 outbound + 2 warmup |
| Reply-to-demo conversion | 20-35% | Positive replies convert well once compliance posture is pre-answered; expect a committee step after the demo |
| Time to first campaign | Same day | ~60 minutes to provision on ColdRelay, plus persona and sequence setup in Apollo |
What It Costs: Apollo + ColdRelay
You pay per mailbox per month for the infrastructure, with volume tiers that drop as you scale (see the table below). DNS, dedicated IPs, and isolated Azure tenants are included.
Apollo is billed separately on its own per-seat plans, which cover the contact database, personas, sequences, and dialer — priced per its current tiers.
Infrastructure cost scales with mailbox count; Apollo's cost scales with seats and data credits. The two stack cleanly — one bill for sending capacity, one for the data and sequencing layer on top of it.
| 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; Apollo handles the sending, sequencing, and inbox rotation on top.
Frequently Asked Questions
Does ColdRelay replace Apollo?
No — they're complementary layers of the same stack. Apollo provides the contact database, specialty filters, personas, and sequences. ColdRelay provides the underlying domains, mailboxes, and dedicated IPs that Apollo's sequences send from. Healthtech teams use them together: ColdRelay for infrastructure, Apollo for data and sending.
Is cold emailing practices and clinics a HIPAA problem?
Cold email to business contacts is not a PHI activity. Your Apollo lists should contain only business contact data — names, titles, work emails, practice addresses — and never anything touching patient information. That keeps prospecting cleanly outside HIPAA's scope. Separately, stating your product's HIPAA posture early in the sequence matters, because it's the first question compliance-conscious buyers ask.
Do ColdRelay mailboxes need a warmup period before Apollo can send?
No waiting period. Warmup runs continuously as part of each mailbox's daily budget — 2 warmup sends/day alongside 2 outbound sends/day, 4 total. Mailboxes arrive with SPF, DKIM, and DMARC pre-configured and are ready to send in about an hour, so you can link them under Settings → Mailboxes in Apollo and launch the same day.
How many mailboxes does a healthtech team need for Apollo sequences?
Work backward from sends. At 2 outbound sends/day per mailbox, 50 mailboxes gives 100 sends/day and 150 gives 300/day. Given healthcare's longer committee-driven cycles, most teams start at 50-100 mailboxes across a couple of secondary domains (ColdRelay supports 100-150 mailboxes per domain) and add capacity as specialty segments prove out.
