Residential solar and EV email has a spam reputation, and utility procurement teams delete anything that reads like a mass blast. We build nurture sequences around your actual sales timeline – quote to install to financing on the residential side, RFP cycle and regulatory triggers on the B2B side – so messages get opened because they're useful, not because they're loud.
The Problem
Sender reputation is already damaged before you send your first email
Residential solar and home-energy email domains inherit a bad neighborhood problem: so many competitors blast unverified, purchased, or scraped lists that spam filters treat the entire category with suspicion. A legitimate homeowner who requested a quote can still see your follow-up land in spam because your domain, or your ESP's shared IP pool, has been trained to look like the aggressive lead-gen operators next door. The result is quoted leads who never see the financing email that would have closed them.
Nurture stops the moment the quote goes out, right when the buyer needs it most
A solar or home-battery purchase runs from first quote through financing approval through permitting through install, often four to nine months end to end. Most companies email hard during the two weeks around the quote, then go quiet, then wonder why a warm lead ghosts during the financing paperwork or interconnection wait. That silence is exactly when a competitor's rep calls, or the homeowner talks themselves out of the purchase. The company that stays useful through permitting delays and financing questions is the one that still has the deal when it's time to sign.
B2B and utility-facing programs miss the actual buying window
Utilities, municipal buyers, and industrial energy customers don't buy off a monthly newsletter. They buy on an RFP calendar, or in the weeks after a regulatory shift – an ITC/PTC change, a new interconnection rule, a state clean-energy mandate. A generic drip that ignores those windows either arrives too early to matter or too late to be considered, and account-based nurture that should be tied to a specific procurement cycle gets treated like commodity marketing email and archived unread.
Buzzword-heavy copy triggers the exact skepticism it's trying to overcome
Climate investors, industrial buyers, and technically literate homeowners have all been pitched vague sustainability claims before, and greenwashing fatigue is real in this category. An email that leans on words like sustainable and revolutionary without a system spec, a real payback number, or a compliance detail reads as filler to a buyer who's evaluating three vendors on technical merit. That copy doesn't just fail to convert, it actively lowers trust in the sender for every email that follows.
How We Help
We start with an audit, not a campaign brief: domain authentication (SPF, DKIM, DMARC), actual inbox placement rather than self-reported opens, and every existing sequence mapped against real buying stages – quote requested, quote sent, financing presented, permitting, install scheduled, install complete. Most CleanTech email programs we inspect run one sequence across all of that, which is the root cause of the mid-cycle silence buyers experience.
From there we build two tracks, because a residential buyer and a utility procurement officer aren't the same audience. The residential track covers the full quote-to-install-to-financing arc, with distinct messages for financing hesitation, permitting delays, and installer scheduling, plus a post-install lifecycle program: referral asks timed to system activation, monitoring-app engagement nudges, and maintenance reminders tied to real equipment schedules.
The B2B and utility track is account-based. Sequences run against a specific buyer's RFP calendar where we have visibility, and against regulatory trigger events where we don't – an IRA guidance update, an ITC step-down, a state interconnection rule change – so outreach lands when the buyer has a reason to be evaluating vendors.
Execution is deliverability-first: dedicated sending domains with proper warmup, list hygiene that removes the purchased or scraped contacts common in this category, and copy that leads with the technical specifics a skeptical buyer wants – system specs, real financing math, interconnection timelines – instead of urgency language borrowed from high-pressure solar sales scripts.
Measurement tracks inbox placement, reply rate, and movement between sales stages, not opens and clicks in isolation. For residential programs that's quote-to-install conversion and post-install referral activity. For B2B programs that's meetings booked around an RFP or regulatory trigger.
What makes this different from a traditional agency retainer is that we work as a fractional, embedded team inside your CRM and ESP, not a vendor producing reports from the outside. The people building your sequences have run growth inside operating companies, so recommendations account for how permitting delays and utility procurement calendars actually behave.
What we deliver
- Deliverability audit and sender reputation rebuild (SPF/DKIM/DMARC, list hygiene, domain warmup)
- Residential quote-to-install-to-financing nurture sequence architecture
- Post-install lifecycle program covering referral, monitoring-app engagement, and maintenance
- B2B account-based sequences tied to RFP calendars and regulatory trigger events (IRA, ITC/PTC, interconnection rules)
- Monthly deliverability and sales-stage progression reporting
The fastest way to kill a cleantech email program is to email like every other solar company – buyers in this category can smell a mass blast before they open it, and a damaged sender reputation costs you leads you already paid to acquire.
Our Methodology
We run CleanTech & Energy email engagements as a 90-day sprint in three phases, not an open-ended retainer. Days 1-30 are audit and infrastructure: authentication setup, list hygiene, inbox placement testing, and mapping the buyer journey stage by stage so we know exactly where the current program goes silent. Days 31-60 are build and launch: residential and B2B sequence tracks go live, domain warmup continues, and we start capturing reply and stage-progression data instead of guessing at what's working.
Days 61-90 are measurement and refinement, including layering in regulatory-trigger automation so a policy or interconnection change fires an outbound sequence instead of waiting for a manual campaign brief. By day 90 you have a working system, not a strategy deck.
The difference from a traditional agency is no months-long onboarding before anything ships, and no handoff between a strategist who scoped the work and a junior account manager who executes it. One embedded, fractional team owns the sequence from audit through send through report.
How We Work
The first 30 days are heaviest on our side: domain and list audit, journey mapping, and stakeholder interviews with your sales team to understand where deals actually stall between quote and install. You'll see a deliverability baseline and a sequence architecture proposal before day 30 closes.
Days 30-60 shift to build and launch. We work inside your existing ESP and CRM rather than asking you to migrate platforms. Weekly check-ins during this phase are short and specific: what shipped, what the early reply and placement data shows, what's next.
By days 60-90 the cadence settles into a steady rhythm – biweekly reviews of sequence performance and pipeline-stage movement, plus ad hoc sequences triggered by a regulatory change or an RFP window opening. The team on your side is a fractional lead who owns strategy and one execution partner handling copy and build, not a rotating bench of contributors.
What clients should expect: direct access to the people doing the work, no monthly report that surfaces problems you already knew about, and a program built to survive us stepping back once it's running.
- Improved inbox placement and lower spam-complaint rates on sending domains
- Longer-horizon nurture that keeps quoted-but-not-installed leads engaged through financing and permitting
- Higher post-install engagement, including referral response and monitoring-app activity
- Better-timed B2B outreach aligned to RFP windows and regulatory trigger events

Frequently asked questions
How much does email marketing cost with Winston Francois?
Most CleanTech & Energy email engagements run $6,000 to $15,000 per month depending on whether you need one track (residential or B2B) or both, and how much sender-reputation repair work is needed at the start. Companies coming in with a damaged sending domain typically need more infrastructure work in month one, which is scoped and quoted before the sprint starts, not added as a surprise later.
How long until we see results from a new email program?
Deliverability improvements from authentication and list hygiene are usually visible within the first 30 days. Pipeline impact takes longer because it depends on your sales cycle – a residential solar buyer moving through financing and permitting won't convert on the same timeline as a click-through metric, so we set expectations around sales-stage movement by day 60 and full-cycle conversion data by day 90 or later.
Do you become part of our team or just deliver reports?
We work embedded inside your CRM and ESP, not as an outside vendor producing monthly PDFs. Your sales team gets direct access to the person writing the sequences, and we sit in on the same pipeline conversations your internal team has, because sequence timing depends on knowing where deals actually stall.
How is this different from a traditional marketing agency?
A traditional agency retainer usually separates strategy from execution across different people, with a months-long onboarding period before anything ships. We run a fixed 90-day sprint with one fractional team that owns the work end to end, and we build inside your existing tools instead of requiring a platform migration, which is where a lot of agency engagements lose their first quarter.
How do you measure ROI on a cleantech email program?
We track inbox placement, reply rate, and movement between real sales stages – quote sent, financing approved, install scheduled – rather than opens and clicks in isolation. For B2B programs, the relevant measure is meetings booked in the window around an RFP or regulatory trigger, since that's what the sequence is actually built to produce.
Can you fix a sender reputation that's already been damaged by aggressive email in the past?
Yes, though it takes deliberate work rather than a quick fix. That usually means a new or re-warmed sending domain, tightened list hygiene to remove purchased or scraped contacts, and a period of lower-volume, higher-relevance sending before we scale back up, since inbox providers rebuild trust based on recent sending behavior, not history alone.
Is Winston Francois a good fit for our company?
This works best for CleanTech and Energy companies with a real sales process to nurture – residential solar, battery storage, EV charging, or grid software companies selling into utilities or industrial buyers – rather than companies looking for a one-off email blast. If your sales cycle is measured in months and your current email program is a single generic drip, that's the exact gap this engagement is built to close.
