How to start B2B outbound: targeting, sequence, follow-ups, measurement

Outbound means you contact companies that did not ask to hear from you, because you have good reason to think you can help them. Done well, it is a short, relevant, respectful message to the right person. Done badly, it is spam that damages your domain and your reputation. This guide walks through a first campaign, in the order you should tackle it.

1. Start with a narrow target

The most common beginner mistake is a list that is too broad. Write down who you sell to in one sentence: the type of company, its size, its country, and the role of the person who feels the problem. That description is your ideal customer profile (ICP).

• Company criteria: sector, size range, country or region, and a visible trait that makes your offer relevant (for example, they are hiring for a role your product helps with).
• Person criteria: the job title that owns the problem and the budget, not just any employee.
• One reason to contact them now: a recent event, a visible need or a clear fit. Without one, your message has no hook.

Begin with a few dozen to a few hundred contacts, not thousands. A small, well-chosen list teaches you more, and a mistake costs less.

2. Build a clean list

Whether you import a spreadsheet or use a data provider, check the quality before sending. Remove duplicates, drop generic addresses that do not point to a person, and verify the email addresses: a high bounce rate hurts your sender reputation quickly. Keep a note of where each contact came from, because you will need it for transparency (see our article on B2B prospecting and GDPR).

3. Prepare your sending infrastructure

Before the first email leaves, your domain must be correctly set up. That means SPF, DKIM and DMARC records, and a sending volume that starts low and grows gradually. Many teams use a separate domain or subdomain for outreach so that a problem never affects the domain used for customer emails. We explain all of it in SPF, DKIM, DMARC and gradual volume.

4. Write a short message with one idea and one ask

A good first email is easy to read in ten seconds. It has four parts:

• A relevant opening line that shows you looked at the company. It must be true and verifiable; an invented compliment is worse than none.
• The problem you think they have, in their words rather than yours.
• What you offer, in one sentence, with a concrete benefit.
• One simple question as the call to action, such as asking whether it is a topic for them, rather than pushing for a long call.

Avoid attachments, heavy images and many links. Write like a person writing to another person. If you use AI to draft messages, keep a human review step and only mention facts you can source.

5. Plan the follow-ups

Most replies come after a reminder, because people are busy and the first email often arrives at the wrong moment. A simple sequence is enough to start:

• Email 1: the introduction described above.
• Email 2, a few days later: a short reminder that adds something new, such as a relevant example or a different angle, rather than repeating "just checking in".
• Email 3, a few days after that: a polite closing message that makes it easy to say no or to point you to the right person.

These intervals are a starting point, not a rule: test them. Two rules matter more than the exact timing. First, stop the sequence as soon as someone replies, whatever the answer. Second, respect any request to stop immediately. You can add a call or a manual LinkedIn message as an extra step in the sequence, but keep the volume and the frequency reasonable.

6. Measure, then change one thing at a time

Track what happens at every stage: emails delivered, bounces, replies, positive replies and meetings booked. Replies and meetings tell you far more than opens. When something underperforms, change one variable at a time (the subject line, the opening line or the offer) so you know what caused the difference. Our guide on measuring a campaign explains the metrics and how to run an A/B test properly.

A realistic first month

• Week 1: define the ICP, build and clean a small list, set up the domain and mailboxes.
• Week 2: write the sequence, send the first small batch at low volume, read every reply yourself.
• Week 3: adjust the message based on real answers, increase volume gradually if bounces stay low.
• Week 4: compare variants, keep what works, and widen the target only once the first segment performs.

Outbly brings these steps into one workspace: ideal customer profile, lead import and search, AI research with sources, sequences sent from your own mailboxes with daily limits, one inbox for replies and a built-in CRM. Drafts wait for your approval by default. You can create an account and try it on a small first list.
