In April 2026, we ran an outreach campaign targeting B2B SaaS founders at companies with 10–50 employees. Four emails over 14 days, 142 contacts, 23 booked meetings. Here's the exact sequence — subject lines, copy, timing, and the metrics behind each step.
The context
Audience: Founders and co-founders at early-stage SaaS companies. Identified via LinkedIn Sales Navigator — filtered by title, company size, and growth signals (recent funding, hiring). List was verified before import.
Inbox: Warmed for 30 days before campaign launch. Reputation score: 87. Daily send limit: 50. Campaign sent to 142 contacts over 3 days.
Step 1 — Day 0: The opener
Subject: quick question, {{first_name}}
Body:
Came across [Company] while researching SaaS teams that are actively hiring — you're clearly growing fast.
One question: are you generating pipeline through cold outreach, or mostly through inbound and word of mouth?
Asking because we help teams like yours build the outbound infrastructure from scratch — inboxes, sequences, and deliverability. Happy to share what's been working.
Worth a quick chat?
Vivek
Results: 52% open rate, 8% reply rate. Most replies were either "yes, interested" or "we do mostly inbound." Both are useful signals.
Why it works: Short, specific, one question. No pitch, no features list. The personalisation (mentioning they're hiring) takes 2 seconds to check on LinkedIn but signals you actually looked at their company.
Step 2 — Day 3: The value add
Subject: Re: quick question, {{first_name}} (bumping this up)
Just sending this up in case my last note got buried.
Thought this might be useful either way: we did a quick analysis of 500 cold email campaigns run on Inboxrise over the last 90 days. The three things that mattered most for reply rate:
1. Inbox reputation (accounts for ~40% of deliverability outcome)
2. Subject line length — under 6 words outperformed longer ones by 2.3×
3. Email length — under 100 words got 1.8× more replies than 200+ word emails
Happy to share the full breakdown. And if cold outreach is something you're thinking about, I can show you what's working for similar teams.
Vivek
Results: 38% open rate, 5% reply rate. The "just sending this up" opener consistently outperforms "following up" — it's less formal and doesn't imply the recipient owes you a reply.
Step 3 — Day 7: The social proof
Subject: what [similar company] did in their first 30 days
Thought this was worth sharing: Stackbloom (another early-stage SaaS team, ~20 people) used Inboxrise to book 14 demos in their first month of cold outreach. No prior outbound infrastructure. One inbox, 50 contacts/day.
Their reply rate was 11% — about 4× the industry average. The main difference was sending from a warmed inbox vs. a cold one.
If you're thinking about building an outbound channel, I can walk you through their setup in 20 minutes. No commitment.
Worth it?
Vivek
Results: 31% open rate, 2% reply rate. Lower reply rate — but the replies were higher intent. Three of the 23 total meetings came from this step alone.
Step 4 — Day 14: The break-up
Subject: closing the loop, {{first_name}}
I'll stop following up after this — I don't want to clog your inbox.
If cold outreach ever becomes a priority, I'd be happy to reconnect. Until then, good luck with everything at [Company] — it looks like you're building something real.
Vivek
P.S. Happy to send over the deliverability guide we put together, no strings. Just reply "guide" and I'll send it over.
Results: 44% open rate, 6% reply rate. Break-up emails consistently have higher open rates than middle-sequence emails — people open them out of curiosity. The P.S. generated a surprising number of "guide" replies, which opened real conversations.
What didn't work (lessons learned)
- Contacts who hadn't opened any of the first three emails rarely responded to the break-up. Consider pausing non-openers after step 2.
- The "similar company" in step 3 needs to be actually similar — using a generic comparison hurt response rate in a segment where we used a less relevant example.
- Subject lines with the company name personalisation performed 15% better than first-name-only subject lines.
The meta-lesson: The sequence that booked 23 meetings wasn't clever. It was short, specific, and human. It demonstrated knowledge of the prospect's situation and offered something useful. That combination, delivered to a warm inbox, is the formula.
