If you're running a Buy Now Pay Later company, you know the real problem isn't your product - it's that merchants don't know you exist, and the ones who do are drowning in pitches from every BNPL startup that launched in the past three years.
Cold email should be your fastest way to get in front of merchants at scale. But BNPL is different from other fintech plays. Your buyers care about one thing above everything else: will this actually increase conversions and AOV without killing my margins? And they're skeptical because they've heard it all before.
Here's what actually works when you're selling BNPL to merchants.
Find the Right Buyers - And They're Not Who You Think
Most BNPL companies target CFOs or finance teams. Wrong move. The person who cares about BNPL adoption is the VP of Revenue or Head of Growth. These are the people measured on conversion rate and AOV. The CFO only cares once you're already live.
Even better: find companies that just raised funding or launched a new product line. Why? Because they're under pressure to hit growth numbers and they're actively looking for conversion levers. Use LinkedIn filters for funding announcements or job postings for revenue roles at your target merchants.
The second-best segment: merchants running promotions or seasonal sales. BNPL crushes during high-ticket seasonal periods. If you can find companies running Q4 holiday campaigns, they're thinking about conversion optimization right now.
Lead with the Specific Conversion Lift, Not the Feature
Nobody cares that you have "seamless checkout integration" or "instant approval rates." They care about one number: how much more revenue will I make?
Do not open with your product. Open with a specific conversion uplift metric from similar merchants. If you've worked with 10+ e-commerce brands, you know the actual range of AOV lift or conversion lift. Use that.
Here's a real opening line that works:
We've helped 12 mid-market e-commerce brands increase their average order value by 18-26% just by offering BNPL at checkout - without changing anything else about their funnel.
Notice what's in there: a specific number, a specific outcome (AOV lift, not "better payment options"), a specific segment (mid-market e-commerce), and social proof (12 brands). This is not a guess - you should only write this if you actually have the data.
If you don't have data yet, be honest. Say: "We've seen conversion uplifts ranging from 12-20% at brands in your category when we've run pilots." Still specific, still credible.
Show Them the Math, Not the Vision
BNPL merchants want to see what this does to their bottom line. Calculate the economic impact for them right in the email. This is not a follow-up conversation item - do it now.
Find a public metric from their site (traffic, rough AOV from their product pages) and do the math:
- Estimated monthly transactions: X
- Current AOV: $Y (you can research this)
- Projected AOV lift with BNPL: +15% = $Y * 1.15
- Incremental monthly revenue: (X * ($Y * 1.15)) - (X * Y)
Show this calculation in your email. One to two lines, max. The math makes it real.
Based on your traffic and typical AOV for your category, BNPL would likely add $8-12K in incremental monthly revenue - which is why merchants like you are adopting it.
That's not vague. That's not theoretical. That's a specific number they can take to their finance team.
Address the Risk Head-On
Merchants are worried about two things: (1) Will this hurt my relationship with my payment processor? (2) What happens if the BNPL company goes under or changes terms?
Don't wait for them to ask. Address it in your email or first follow-up.
"We integrate with [Stripe/Square/your processor] as a payment method, not a replacement. Your existing processing relationship doesn't change. We handle the credit risk and funding - you just get the higher AOV."\p>
For the second worry: mention any regulatory backing, funding rounds, or established partners you have. If you're backed by serious investors or integrated with major platforms, say it. Merchants need to believe you'll still be around in 18 months.
The Subject Line Needs to Signal Relevance Immediately
Subject lines for BNPL need to do one thing: make them believe this is relevant to their current goals, not a generic pitch.
Generic: "New payment option for [Company]"Better: "AOV lift for [Company]'s checkout"Best: "Quick question on [Company]'s Q4 strategy"
The best subject lines reference something specific about them. If they just launched a holiday campaign, reference that. If they're in a specific vertical you've had success in, reference it.
18-26% AOV lift we're seeing with brands like [Similar Competitor]
This works because it's specific, it references a competitor, and it leads with the outcome. No fluff.
Follow-Up Sequence Matters More Than Your First Email
Your first email gets maybe 20% response rate if it's good. The follow-up is where you convert the people who were interested but didn't respond, or were confused.
Follow-up 1 (2 days later): Add new information. If your first email mentioned AOV lift, mention checkout friction or cart abandonment recovery. Different angle, same goal.
Follow-up 2 (4 days later): Social proof. Mention a specific competitor or similar merchant that went live. "We just onboarded [Competitor], they saw results in 30 days."\p>
Follow-up 3 (7 days later): Lower the ask. "Not interested in a call - would you be open to a 15-minute async walkthrough of how this works?" Sometimes yes is easier than no when the barrier is lower.
Most BNPL companies stop after one email. The meetings happen in the follow-up sequence.
Segment Your Outreach by Merchant Vertical
BNPL works differently for apparel vs. consumer electronics vs. furniture. Your opening line should reflect that you understand their specific problem.
Furniture merchants care about: high AOV, seasonal demand spikes, customers on fixed budgets.Apparel merchants care about: frequency of purchase, building repeat customers, reducing return friction.Electronics merchants care about: high-ticket items, credit-constrained buyers, competitive margins.\p>
Your email should reference the right metric for their vertical. This isn't personalization theater - it's showing that you've done basic research on their category.
When to Bring in Help
Cold email for BNPL is straightforward if you have product-market fit and real conversion data. But running this at scale - building accurate merchant lists, writing vertical-specific campaigns, managing follow-up sequences, tracking what actually converts - is a different animal.
If you've validated that merchants respond when you do this right, but you don't have the bandwidth to build lead lists, write variations for each vertical, and track conversion metrics by segment, that's where it gets painful. You either hire someone to do it, or you bring in a team that specializes in this. Many BNPL companies find it faster to outsource the execution while they focus on onboarding and product.
