Coaching Outbound, Run Through Instantly
Coaching is the one business where the sender genuinely is the product. When a founder or exec gets a cold email from a coach, they're not evaluating a tool — they're evaluating you: your judgment, your tone, whether a discovery call with you would be worth 30 minutes. That makes coach outbound different from typical B2B blasting: smaller lists, heavier personalization, and copy that has to sound like a person, not a pipeline.
Instantly is where that happens — the campaign builder, the variants, the Unibox where you handle replies yourself. ColdRelay is the infrastructure underneath: the secondary domains, mailboxes, and dedicated IPs Instantly actually sends from, so your personal domain — the one carrying your newsletter and client conversations — never touches cold email. This guide covers how to wire the two together.
Why Run Instantly on ColdRelay Infrastructure
Instantly is a sending and sequencing platform — it sends from whatever mailboxes you connect to it. It doesn't provision the domains or guarantee the deliverability of the mailboxes themselves; that's the infrastructure layer's job.
For a coach, that layer matters more than usual. Your primary domain is where your newsletter, your client communication, and your referral threads live. One bad cold campaign from that domain and the emails your business actually runs on start landing in spam. ColdRelay keeps cold sending entirely separate: dedicated mailboxes on isolated Azure tenants with dedicated IPs, fully DNS-configured (SPF, DKIM, DMARC) and ready in about an hour — with 95%+ inbox placement, so your carefully written emails actually get read.
The pairing is additive, not competitive: ColdRelay is the infrastructure, Instantly is the sender on top. You keep Instantly's campaign builder, variant testing, and Unibox — you just give it mailboxes built to land, on domains that aren't yours to lose.

Provision mailboxes on ColdRelay
Pick one or two secondary domains close to your personal brand — if you coach at janedoe.com, something like janedoecoaching.com or talkwithjane.com. ColdRelay supports 100-150 mailboxes per domain, but most coaches start far smaller: 10-30 mailboxes is plenty for a tightly qualified list. Everything provisions on isolated Azure tenants with dedicated IPs in about an hour, with SPF, DKIM, and DMARC already configured.
Export the mailbox credentials
From the ColdRelay dashboard, export your mailbox list with SMTP/IMAP credentials. ColdRelay's CSV export matches the column layout Instantly expects, so there's no manual reformatting.
Add the accounts in Instantly
In Instantly, go to Email Accounts → Add New → Bulk Import via CSV (or connect via IMAP/SMTP one at a time). Each ColdRelay mailbox connects as its own sending account so Instantly can rotate sends across all of them.
Set sending limits to match the budget
Set each account's daily campaign limit in Instantly to 2 outbound emails per day to mirror ColdRelay's per-mailbox budget — 4 sends/day total per mailbox, split 2 outbound + 2 warmup. ColdRelay's warmup runs continuously as part of that budget, so there's no waiting period before your first campaign and no need to double-warm inside Instantly.
Build the campaign, upload your list, launch
In Instantly's campaign builder, upload your prospect CSV, map your personalization fields, and write 2-3 subject line and body variants — testing which version of your voice converts is where Instantly earns its keep for coaches. Attach all connected mailboxes, then work replies personally from the Unibox.
The Coaching Instantly Playbook
Protect your personal domain at all costs
Your newsletter, client threads, and referral intros all run on your primary domain — its reputation is the business. Every cold sequence goes through ColdRelay secondary domains in Instantly; your personal domain never sends a single cold email.
Small list, heavy qualification
A coach doesn't need 10,000 prospects — you need the 300 founders or execs who actually fit your niche. Spend list-building time on qualification, not volume, and use Instantly's custom variables to reference something real about each person. At coaching volumes, ten minutes of research per 20 prospects pays for itself in replies.
Sequence to the offer ladder, not the program
Nobody buys a $15k coaching program from a cold email. Structure your Instantly sequence around the first rung: a genuinely useful free resource or a 20-minute discovery call. The program pitch happens on the call — the email's only job is to start a conversation that sounds like you.
Treat the Unibox like your own inbox
When a prospect replies, they think they're talking to you — so it has to be you. Work Instantly's Unibox personally and daily; a thoughtful same-day reply from the actual coach is the whole pitch. Canned responses or a VA answering in your name undo everything the personalization bought.
Typical Coaching Outbound Benchmarks (Instantly + ColdRelay)
| Metric | Benchmark | Notes |
|---|---|---|
| Inbox placement rate | 95%+ | Dedicated IPs and isolated tenants outperform shared Google/Microsoft pools |
| Reply rate | 4-9% | Small, tightly qualified lists with real personalization sit well above B2B averages |
| Mailboxes per coach | 10-30 | 20-60 outbound sends/day of capacity — plenty for a qualified niche list |
| Outbound capacity per mailbox | 2/day | 4 sends/day total per mailbox — 2 outbound + 2 warmup |
| Time to first campaign | Same day | ~60 minutes to provision, plus campaign setup in Instantly |
What It Costs: Instantly + ColdRelay
You pay per mailbox per month for the infrastructure, with volume tiers that drop as you scale (see the table below). DNS, IPs, and isolated Azure tenants are included — and at coaching volumes of 10-30 mailboxes, the total infrastructure line stays small.
Instantly is billed separately on its own subscription for the campaign builder, variant testing, and Unibox — priced per its current plans.
Infrastructure cost scales with mailbox count; Instantly's cost scales with plan features. For a solo coach the combined stack typically costs less than one month of most coaching retainers — one bill for sending capacity, one for the sending software.
| 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; Instantly handles the sending, sequencing, and inbox rotation on top.
Frequently Asked Questions
Does ColdRelay replace Instantly?
No. They do different jobs. Instantly handles campaigns, variant testing, and reply management through the Unibox. ColdRelay provides the underlying domains, mailboxes, and dedicated IPs that Instantly sends from. You use them together — infrastructure underneath, sending software on top.
Will cold email hurt the domain I use for my newsletter and clients?
Not when the mailboxes come from ColdRelay. Cold sending runs on separate secondary domains, dedicated IPs, and isolated Azure tenants — completely walled off from your personal domain. Your newsletter, client threads, and referral intros keep their reputation untouched.
Do I need to wait through a warmup period before my first campaign?
No. ColdRelay mailboxes warm continuously as part of the standard send budget — 4 sends/day per mailbox, split 2 outbound + 2 warmup. You can launch your first Instantly campaign the same day you provision, and you don't need to run Instantly's separate warmup on top.
How many mailboxes does a coach actually need?
Far fewer than a typical B2B team. At 2 outbound sends/day per mailbox, 10 mailboxes gives 20 sends/day and 30 gives 60/day — more than enough to work a tightly qualified list of a few hundred founders or execs with real personalization. Start small and add mailboxes on ColdRelay only if your niche list genuinely supports more volume.
