You don't need an SDR to start outbound. You need a narrow list, a short email, and a week of focused setup.
This guide walks through your first campaign as a founder, with two example emails, a follow-up plan, and a checklist you can start on Monday.
Pick an ICP narrow enough to write one email for
The most common founder mistake is a list that's too broad. "B2B SaaS companies" is not an ICP. "Heads of Customer Success at 50 to 200 person SaaS companies that just raised a Series A" is.
A useful test: can you write one email that feels specific to every person on the list? If not, narrow further.
Write down three things:
- Who: one job title family, one company size band, one or two industries.
- Trigger: something that makes the problem urgent right now, like a funding round, a new hire, a job post, or a tool migration.
- Problem: the one pain you solve that this person feels personally.
Your first customers are the best source here. Look at who said yes fastest and describe them.
Build a list of 200 to 500 contacts
Start small on purpose. 200 to 500 contacts is enough to learn what works and small enough to review by hand.
Common sources: LinkedIn searches, B2B data providers, job boards (for hiring triggers), and funding announcements.
For each contact, collect first name, company, title, verified work email, LinkedIn URL, and one line of context. That context column is what makes the email feel written for them.
Verify every email before sending. Bounces hurt sender reputation, and a new domain has little to spare. Remove customers, investors, and anyone you're already talking to.
Set up separate sending domains and inboxes
Don't send cold email from your main company domain. If something goes wrong, you want the domain your team, customers, and investors rely on kept out of it.
The usual setup is two or three secondary domains that look like your brand (getacme.com, tryacme.com), each with two or three inboxes and SPF, DKIM, and DMARC configured. New inboxes need warmup before real sending. A common starting point is two to three weeks of warmup, then a modest daily volume per inbox that you increase slowly.
The full walkthrough is in setting up domains and inboxes for cold email. In SuperSend you can buy Google or Outlook inboxes and domains directly, or connect the Google Workspace and Outlook inboxes you already have, and warmup runs on every inbox.
Write a short first email
You have an advantage no SDR has: you built the thing. Use it. Keep the first email between 50 and 120 words, plain text, with one clear ask and no links, images, or attachments.
Example 1: trigger-based
Subject: onboarding after the raise
Hi {{firstName}},
Congrats on the Series A. The next few months usually mean a lot more new accounts going through onboarding with the same small CS team.
I'm the founder of [Company]. We flag accounts that stall in their first 30 days so your team can step in before they quietly churn. [One proof point you can stand behind, like who uses it.]
Worth a 15 minute look, or is onboarding not a priority this quarter?

Example 2: problem-first question
Subject: month-end close at {{company}}
Hi {{firstName}},
Quick question: how long does month-end close take your team right now?
When I talk to agency finance leads, most of that time goes to chasing timesheets and matching project invoices by hand.
I'm the founder of [Company]. We connect time tracking and invoicing so most of the close is done before the month ends.
If that sounds familiar, I can send a 2 minute video of how it works. If not, no worries.

Why these work
| Element | Why it helps |
|---|---|
| Short, lowercase subject | Reads like a note from a person, not a newsletter |
| First line about them | A trigger or a question earns the second line |
| One sentence of problem | Uses words the buyer would use, not your feature names |
| "I'm the founder" | Busy people reply to founders more readily than to a generic rep |
| One small ask | Example 1 offers an easy "no", which still starts a conversation. Example 2 offers a video instead of a call. |
| No links or images | Lighter for deliverability and feels less like marketing |
Plan three follow-ups
Many replies come after the first email, so plan a short sequence before you launch. A simple starting structure:
| Day | Step | What to say |
|---|---|---|
| 1 | Email 1 | The first email above |
| 3 | Email 2, same thread | One or two lines adding a detail you left out |
| 7 | Email 3 | A different angle: a specific use case or short story |
| 12 | Email 4 | A short close: "Should I stop reaching out about this?" |
Every follow-up should add something new. Stop the sequence as soon as someone replies. For more on spacing and examples, see how many follow-ups to send.
Add LinkedIn touches
A second channel makes your name familiar before the second email lands. A light pattern:
- Day 1: visit their profile, then send email 1.
- Day 2 or 3: send a connection request, with no note or a one-line note that doesn't pitch.
- Once connected: a short message that references something specific, not a copy of your email.
Two cautions. LinkedIn doesn't publish exact limits, and commonly cited guidance ranges widely, so start with a small number of requests per day and increase slowly. LinkedIn's terms also restrict automation tools, so if you automate, accept that risk knowingly. SuperSend puts LinkedIn steps in the same sequence as your emails, and a reply on either channel stops both. More in running cold email and LinkedIn in one sequence.
What "good" looks like early
Reply rates vary a lot by market, offer, list quality, and deliverability. You'll see figures quoted from under 1% to well over 10%, and both can be true for different teams. Treat any number you read as a wide range, not a target.
With a few hundred contacts, the numbers are noisy. Watch these instead:
- Bounce rate. A common rule of thumb is to keep it under 2 to 3%. Higher than that usually means a list problem.
- Any replies, including "no". That means you're reaching inboxes and people understand what you do.
- Positive replies per 100 contacts. Compare this between weeks and segments, not against other companies.
- Who is replying. Are they people you would actually want as customers?
If you get zero replies after the full sequence to a few hundred people, check deliverability first (an inbox placement test helps), then the list, then the message.
Read replies and iterate weekly
Sort every reply into a bucket. Each one tells you what to change.
- Interested: reply fast, same day if you can.
- Wrong person: thank them and ask who owns it. Lots of these means your title targeting is off.
- Not a fit: lots of these means your ICP is off.
- Not now: note the reason and follow up in 60 to 90 days.
- Silence: usually the message, sometimes deliverability.
Block 30 minutes every Friday. Read every reply and change one thing for next week: the subject line, opening line, ask, or segment. Change everything at once and you won't know what worked. With small lists, only trust big differences between A/B variants.
When to hand off to an SDR
Hiring a rep before you've found a message that works means paying someone to figure out what you haven't. Hand off when most of these are true:
- The same ICP and sequence book meetings most weeks.
- You've closed deals that started from cold outreach.
- You can write the playbook down: ICP, list sources, sequence, and answers to common objections.
- Outbound is crowding out product work or closing.
Hand off list building and the sequence first. Keep taking first calls yourself for a while.
One-week launch checklist
If your inboxes are new, this week is setup, and real sending starts once warmup has run. If you already have warmed inboxes, launch on Friday with a small batch.
- Monday: write your ICP in one paragraph. Buy two or three secondary domains, create inboxes, set up SPF, DKIM, and DMARC, and start warmup.
- Tuesday: build a list of 200 to 500 contacts with a context column. Verify every email and remove existing customers and conversations.
- Wednesday: write email 1 and three follow-ups. Draft two subject lines to test. Read everything on your phone.
- Thursday: build the sequence with a send window in your prospects' time zone, low daily limits per inbox, LinkedIn steps, and stop-on-reply. Run an inbox placement test.
- Friday: send to your first 50 contacts (once inboxes are warmed), set up your reply buckets, and book your weekly 30 minute review.
The short version
- Pick an ICP narrow enough that one email fits everyone on the list.
- Start with 200 to 500 verified contacts and send from separate, warmed domains.
- Keep the first email short, about them, and end with one small ask.
- Plan three follow-ups and a few LinkedIn touches, and stop when anyone replies.
- Read replies weekly, change one thing at a time, and hand off once the playbook repeats.
