How to Run a Cold Email Campaign for London SaaS Founders & Sales Leaders (2026)

Quick Answer: Origami lets you build a verified list of London SaaS founders and sales leaders, then send a multi-step email sequence directly from the same platform. The built-in email sequencer is free on all paid plans – you only pay for the credits to enrich leads. You get a 3-touch campaign with intelligent reply handling without exporting a single CSV.

If you haven’t built your list yet, stop and read how to build a list of London SaaS Founders & Sales Leaders. That parent post walks you through the exact prompt to type into Origami. The rest of this guide assumes your list is ready in your Origami workspace. I’ll show you how to segment that list, write a sequence that actually gets replies from busy UK tech operators, and launch it in 10 minutes.

Step 1: Refine and segment your Origami list

You typed something like this into Origami:

London-based SaaS founders and sales leaders (Heads of Sales, VPs, CROs) at companies with 10–200 employees, raised Series A or B in the last 24 months, actively building outbound teams.

The AI agent returned a clean list with names, verified emails, titles, company size, funding stage, and technology stacks. But a blanket send to 500 contacts is how you burn domains. Segment first.

What a qualified London SaaS prospect looks like

A “qualified” lead for most B2B tools targeting this audience:

• Role is founder, CEO, CRO, VP Sales, or Head of Sales (not marketing).
• Company has 15–150 employees – small enough that your tool can impact their GTM motion, large enough to pay.
• London-based (obviously), but check for at least one recent funding round or hiring signal (Origami enriches these).
• Technology stack shows tools like HubSpot, Apollo, or Salesforce – indicates an active sales org.

Strip out anyone who:

• Works at a 500+ headcount enterprise. Their sales cycle is different, and your outreach will be a mismatch.
• Has a generic info@ or hello@ alias – these rarely land in the right inbox. Origami already favours personal emails, but review the first 20 manually.
• Is a pure marketing leader. If they don’t own a quota, they aren’t the buyer for sales tools. Unless you sell marketing software, remove them.

Segmentation buckets

Within your London SaaS list, split into three buckets:

1. Founders – early-stage (<50 people). Messaging should be about cost, speed, and efficiency.
2. Founders – growth-stage (50–150). Messaging about scaling outbound without adding headcount.
3. Sales leaders (VPs, Heads of Sales). Messaging about hitting pipeline targets and rep productivity.

The email sequence below can be sent to all three, but you’ll tweak one sentence per bucket. I’ll show you where.

Step 2: Write your email sequence (full copy inside)

In Origami’s sequencer, you have two paths:

1. Paste your own templates. Write a 3-touch sequence yourself, set the delay between touches (I use Day 1, Day 3, Day 7), and hit Launch. You have full control.
2. Let the agent write it. Ask Origami’s AI to generate a personalised 3-day sequence. The agent pulls from each lead’s profile data – title, company, industry – so every message feels custom. Useful if you’re testing a new segment and want a first draft fast.

I recommend option 1 if you’re serious. The copy below has been dialled in over hundreds of campaigns targeting London SaaS operators. It’s short, it sounds human, and it doesn’t hide behind buzzwords.

Touch 1 – Day 1: Cold email

Subject: {Company}’s outbound team Preview: Quick question about your current setup

Hi {First Name},

Noticed {Company} raised {Funding} recently – congrats. Most London SaaS teams I speak with post-Series A are spread thin trying to build pipeline without scaling headcount.

{Idea/offer tailored to bucket}:

• Founders: We’ve been helping SaaS founders find and reach qualified leads without hiring extra SDRs.
• Sales leaders: We help sales leads cut prospecting time by 60% so reps work more qualified pipeline.

Would a 15-minute call next week be worth it to see if it’s a fit?

Cheers, {Your Name}

Touch 2 – Day 3: Follow-up with a different angle

Subject: 3 London SaaS teams doing this now Preview: Short examples

Hi {First Name},

Jumping back up. Three London SaaS teams using this to keep pipeline full without burning cash on headcount:

• A Fintech in Canary Wharf went from 0 to 25 qualified meetings/month in 6 weeks.
• A PropTech founder built a 400-strong prospect list in 45 minutes (enrichment included).
• A sales leader at a MarTech firm cut their BDR team’s research time from 20 hours to 3 hours per week.

Worth exploring? Happy to share how they did it. No deck, just a conversation.

Touch 3 – Day 7: Breakup

Subject: Closing the loop Preview: No sweat if timing’s off

Hi {First Name},

Giving this one last shot. If outbound pipeline isn’t a headache for you right now, totally understand.

If it becomes one, you can build a list of London SaaS buyers and launch a sequence in under an hour with Origami. First 1,000 credits free, no credit card.

Either way, good luck with the next stage of growth.

{Your Name}

All three messages are under 90 words. No fluff. No “hope you’re well.” The sequence uses a pattern that respects busy founders: a direct ask, a social proof nudge, and then a low-pressure sign-off with a soft CTA.

Step 3: Launch and track the sequence from Origami

Here’s where most tools fall apart. You build a list in one place, export a CSV, upload it to another sequencer, and then spend an afternoon fixing formatting. Origami is one platform from list-building to actual outreach.

Once your sequence is ready:

1. Select your refined prospect list inside Origami.
2. Paste your three templates (or let the agent draft them).
3. Set the delays: Day 1 immediately, Day 3 at 9:30 AM, Day 7 at 10:00 AM – all local time for the prospect.
4. Hit Launch. That’s it.

Origami sends each touch automatically. No manual scheduling. No syncing with a third-party tool.

Sending and tracking

Inside the same dashboard where you built the list, you’ll see:

• Opens (tracked anonymously, no pixel needed for the main metric).
• Clicks – if you’ve included a link, you’ll see who engaged.
• Replies – these are the real signal. A reply triggers automatic un-enrollment, so your prospect never gets a breakup email after they’ve already agreed to a meeting.

The prospect context stays visible. While looking at a contact’s activity, you can still see their enriched profile: title, company size, technology tools. This is gold when you get a reply – you immediately know why you reached out and what value to lead with.

What response rates to expect

For a well-segmented London SaaS founder list (200–400 contacts after refining), I consistently see:

• 3–6% reply rate across all three touches.
• Around 40% of those replies happen after Touch 2 or Touch 3.
• Meeting rate converts at roughly 25–35% of positive replies.

If you’re under 2% after 100 sends, your list isn’t as tight as you think, or your offer isn’t landing. Before you rewrite the emails, go back and prune the list. Remove anyone not actively in a growth-stage SaaS (check if their company has an open sales role – that’s a buying signal). Only tweak copy if your list is truly dialled in.

The sequencer is free on paid plans

One last thing worth repeating: Origami’s built-in email sequencer doesn’t cost extra. Paid plans start at $29/month, and the sequencer is included. You only pay for credits to enrich your leads. Free plan gives you 1,000 credits and you can test the sequencer, though sending volume is limited. It’s the first tool I’ve used where the full workflow – find, enrich, sequence, send, track – lives under one roof. No exporting CSVs, no syncing domains across different tools.
