Commercial Solar Outbound, Run Through QuickMail
Commercial solar is a B2B sale with a long cycle: a developer or EPC firm prospects facility owners, CFOs, and property managers, offers a free energy-cost analysis of their specific building, and works the deal toward a site assessment. Cold email is one of the few channels that reaches those decision-makers directly — but it only works if the message lands in the inbox.
QuickMail is where your campaigns live: the sequences, inbox rotation, and reply detection. ColdRelay is the infrastructure underneath — the secondary domains, mailboxes, and dedicated IPs that QuickMail actually sends from. This guide covers how commercial solar teams wire the two together: provisioning sending infrastructure on ColdRelay, connecting it to QuickMail, and structuring sequences that turn incentive deadlines and utility rate changes into booked site assessments.
Why Run QuickMail on ColdRelay Infrastructure
QuickMail is a sending and sequencing platform built around deliverability — inbox rotation across senders, a simple campaign builder with attribute personalization, and automatic reply detection. But QuickMail sends from whatever mailboxes you connect to it; it doesn't provision domains or guarantee the reputation of the mailboxes themselves. That's the infrastructure layer's job.
That's exactly where ColdRelay fits. Instead of buying Google Workspace seats one at a time and configuring DNS by hand, you order dedicated mailboxes on isolated Azure tenants with dedicated IPs — SPF, DKIM, and DMARC pre-configured, ready in about an hour, with no warmup waiting period before you can send. You connect those mailboxes to QuickMail and start prospecting.
The pairing is additive, not competitive: ColdRelay is the infrastructure, QuickMail is the sender on top. You keep QuickMail's inbox rotation, personalization attributes, and reply detection — you just give it mailboxes built to land. For solar firms whose pipeline depends on reaching a CFO before an incentive deadline, that 95%+ inbox placement is the difference between a booked assessment and a spam folder.

Provision mailboxes on ColdRelay
Pick secondary domains related to but separate from your primary company domain — your proposals, financing paperwork, and O&M correspondence should never share reputation with cold outreach. ColdRelay supports 100-150 mailboxes per domain; most commercial solar teams start with 30-100 mailboxes across 1-2 domains, often one domain per region or utility territory. Everything provisions on isolated Azure tenants with dedicated IPs in about an hour, with SPF, DKIM, and DMARC already configured.
Add the mailboxes as inboxes in QuickMail
In QuickMail, go to Settings → Inboxes → Add Inbox and connect each ColdRelay mailbox via SMTP/IMAP. ColdRelay's credential export matches the fields QuickMail expects, so connecting a batch is copy-paste work, not configuration work.
Group inboxes for rotation
Use QuickMail's inbox rotation to spread each campaign's sends across your connected ColdRelay mailboxes. Group inboxes by domain or by utility territory so a Southern California Edison campaign and a Con Edison campaign each rotate through their own pool — keeping regional volume balanced and reputation isolated.
Set sending limits to match the ColdRelay budget
Set each inbox's daily sending limit in QuickMail to 2 outbound emails per day, mirroring ColdRelay's per-mailbox budget of 4 sends/day total — 2 outbound + 2 warmup. Warmup runs continuously on ColdRelay's side as part of that budget, so there's no separate warmup period to schedule and no need to double-warm inside QuickMail.
Build the campaign with attributes and launch
Create your campaign in QuickMail's campaign builder and use custom attributes for the fields that make solar outreach convert — facility square footage, estimated annual kWh spend, utility territory, and the relevant incentive deadline. Attach your inbox group, enable reply detection so interested facility owners drop out of the sequence automatically, and launch. With 50 mailboxes you have 100 outbound sends/day of capacity.
The Commercial Solar QuickMail Playbook
Pitch the analysis, not the panels
Facility owners and CFOs don't reply to "go solar" — they reply to numbers about their own building. Lead with a free energy-cost analysis of their specific facility and load profile: "based on your roof area and your utility's current commercial rates, here's the range we'd expect." Use QuickMail attributes to merge in the building-specific details so every email reads like it was written after looking at their site.
Use incentive deadlines as the timing hook
Commercial solar has built-in urgency that most industries would kill for: federal ITC step-downs, state program funding windows, and utility rate-case changes all have real dates. Build separate QuickMail campaigns around each deadline — "your utility's net metering tariff changes in Q4" is a far stronger opener than any generic value prop. When a deadline passes, retire the campaign and spin up the next one.
Segment by utility territory, not just geography
A facility in PG&E territory and one in a municipal utility next door face completely different economics. Segment lists by utility territory and rate schedule, run each as its own QuickMail campaign with territory-specific numbers, and rotate each through its own ColdRelay inbox group. Your reply rates will tell you which territories' economics are resonating.
Sequence to the site assessment, not the contract
Commercial solar deals run 6-18 months — nobody signs from a cold email. The only job of the sequence is to book a site assessment or a 20-minute energy-cost review. Keep the CTA that small, let QuickMail's reply detection pull interested prospects out of the sequence immediately, and hand replies to a human the same day. A property manager who says "send me the analysis" is your pipeline; don't let an automated follow-up land on top of that reply.
Typical Commercial Solar Outbound Benchmarks (QuickMail + ColdRelay)
| Metric | Benchmark | Notes |
|---|---|---|
| Inbox placement rate | 95%+ | Dedicated IPs and isolated tenants outperform shared Google/Microsoft pools |
| Reply rate | 2-5% | Facility-specific energy-cost hooks at the top of the range; generic solar pitches at the bottom |
| Site assessments booked per 1,000 sends | 5-12 | Higher when an incentive or rate-change deadline anchors the sequence |
| 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 on ColdRelay, plus campaign setup in QuickMail |
What It Costs: QuickMail + 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.
QuickMail is billed separately on its own subscription for campaigns, inbox rotation, and reply detection — priced per its current plans.
Infrastructure cost scales with mailbox count; QuickMail's cost scales with plan tier. The two stack cleanly — one bill for sending capacity, one for the sending software. For a solar BD team, the combined stack typically costs less than a single SDR's first week.
| 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; QuickMail handles the sending, sequencing, and inbox rotation on top.
Frequently Asked Questions
Does ColdRelay replace QuickMail?
No. They do different jobs and work together. QuickMail handles campaigns, inbox rotation across senders, attribute personalization, and reply detection. ColdRelay provides the underlying domains, mailboxes, and dedicated IPs that QuickMail sends from. You connect ColdRelay mailboxes as inboxes in QuickMail and run both.
Will cold outreach hurt the domain we use for proposals and financing paperwork?
Not when the mailboxes come from ColdRelay. Outbound runs on separate secondary domains, dedicated IPs, and isolated Azure tenants — completely walled off from the primary domain you use with customers, lenders, and utilities. If a cold domain ever takes reputation damage, your deal-flow email is untouched.
How fast can we launch before an incentive deadline?
Same day. ColdRelay mailboxes provision in about an hour with SPF, DKIM, and DMARC pre-configured, and there's no warmup waiting period before sending — warmup runs continuously as part of each mailbox's 4/day budget (2 outbound + 2 warmup). If a utility rate change or ITC deadline creates a window, you can have a QuickMail campaign sending the same afternoon.
How many mailboxes does a commercial solar team need?
It depends on territory and pipeline targets. At 2 outbound sends/day per mailbox, 30 mailboxes gives 60 sends/day — enough to work one utility territory steadily. Teams covering multiple territories typically run 50-100 mailboxes, often grouped by region in QuickMail, and scale on ColdRelay as new markets open. Each domain supports 100-150 mailboxes.
