How to sell to investors: A data‑backed playbook for earning attention and funding
Investors move fast. Whether they’re venture capitalists, angels, or corporate venture arms, they’re constantly filtering deal flow, scanning market trends, and evaluating pitches — all while juggling portfolio oversight.
To earn their attention, your outreach needs to match their cadence: concise, relevant, and perfectly timed.
Apollo’s analysis of hundreds of thousands of investor‑level email interactions in 2025 uncovered the best times to engage, the themes that get replies, and the messaging frameworks that actually convert interest into conversations.
Best and Worst Times to Email Investors
Note on time zones: All times in this report are recorded in UTC (Coordinated Universal Time). For U.S. recipients, subtract about four to eight hours, depending on the time zone, to get the real sending window.
The right timing isn’t just about avoiding investor “no‑go” hours — it’s about catching them when they’re mentally open to exploring opportunities.
The data shows Thursday at 7 a.m. UTC is the single best slot, driving an 18.56% open rate. In most U.S. time zones, that lands in the early morning hours, when inbox competition is lower and deal‑minded investors are prepping for the day.
Late‑night outreach also works: Sunday at 9 p.m. UTC (Sunday afternoon in the U.S.) sees above‑average performance, likely tied to investors reviewing their upcoming week’s schedule.
The worst times? Late‑night Friday UTC and midday Tuesday — moments when investors are either mentally checked out for the weekend or buried in back‑to‑back meetings.

Actionable Takeaway: Target early morning Thursday UTC (Wednesday night in the U.S.) to catch investors in high‑receptivity mode. Avoid Friday night UTC and midweek afternoon lulls when attention is lowest.
Best Day of the Week to Email Investors
Investors check their inbox daily, but when your email lands has a big influence on whether they actually engage.
Apollo’s dataset shows Thursday is the best day for investor outreach, closely followed by Friday and Monday.
Why Thursday? It’s far enough into the week that urgent portfolio fires are handled, but early enough that there’s still time to act on promising leads before the weekend. Friday’s strength comes from “inbox triage” mode before they sign off. Monday works when your message aligns tightly with their week’s strategic priorities.
Midweek (Tuesday or Wednesday) dips slightly — these are high‑meeting days for most investors. Saturdays lag, as many are offline or focused on personal commitments.
Apollo.io
Actionable Takeaway: Send Thursday morning UTC (Wednesday night in the U.S.) for maximum impact. If you miss that slot, Friday early UTC still delivers strong performance.
Top‑Performing Campaign Types for Investors
Not every investor email lands the same way. The highest‑reply campaigns in this analysis share three traits.
- Specific opportunity framing – They clearly communicate the deal thesis or investment angle.
- Credibility – They include concrete traction, market data, or founder pedigree.
- Low‑friction call to actions – They make it easy to take the next step (e.g., short call, deck review).

Actionable Takeaway: Lead with a clearly defined opportunity, back it with proof, and invite investors into a simple, concrete next step.

What NOT to Do When Emailing Investors

- Hide the ask — be clear on your funding target.
- Blast at random times without timing the strategy.
- Skip research — investors spot spray‑and‑pray instantly.
Key Takeaways
- Thursday early UTC is your prime slot.
- Lead with deal specifics and proof, not fluff.
- Keep your CTA short, clear, and low‑commitment.
