Writing cold emails that book calls: a 5-line framework

Principles before the framework

• Write to one person. If the email could go to anyone, it will feel like it went to everyone.
• Make it about them. Count the sentences that start with "we" or "I". Cut most of them.
• Ask for a reply, not a meeting. A small yes is easier than a big one, and a reply opens the conversation.
• Keep it short. Five sentences or fewer, readable on a phone without scrolling.
• Sound like a person. Plain text, no images, no marketing language.

The five lines

Line 1: A relevant opener

Show you know who they are. Refer to something specific and recent: a job advert, a new service, a post they wrote, a client win. Skip flattery ("love your website!") and get to the point. If you cannot find anything specific, open with something true about their role or sector instead.

Line 2: The problem

Name a problem that people in their position commonly face, linked to the opener where possible. Phrase it as an observation, not an accusation: "Firms growing that quickly often find..." rather than "Your IT is a mess."

Line 3: Proof or a reason to believe

One sentence on how you help, ideally with a real, specific result for a similar business. If you do not have a case study yet, offer insight instead: a short observation that shows expertise. Never invent results.

Line 4: A small ask

Make replying easy. "Worth a quick chat?" or "Would it help if I sent over how we'd approach it?" are easier to say yes to than "Can we book a 45-minute discovery call on Tuesday?"

Line 5: An easy way out

A courteous opt-out such as "If it's not relevant, just say and I won't follow up." It respects the reader, meets UK rules on opt-outs and, oddly, often increases replies. Read the legal background in our UK cold email law guide.

A worked example

Here is the framework applied to an imaginary IT support company writing to a growing accountancy practice. The names are made up.

Subject: new Leeds office

Hi Sarah,

Saw Harper & Cole is opening a second office in Leeds next spring.

Practices at that stage often find their IT was set up for one site and starts creaking when staff split between two.

We look after IT for accountancy firms across Yorkshire, including office moves and new-site setups.

Worth a short call to compare notes before the move?

If the timing's wrong, just say and I'll leave it there.

Tom

Under a hundred words, one clear reason for writing, one small ask. See how we apply this for IT and managed service providers.

Subject lines

The best cold subject lines look like internal emails: two to four words, lower case, specific. "new Leeds office", "sales hiring", "question about onboarding". Avoid clickbait, fake "Re:" or "Fwd:" prefixes, and anything that would look at home in a promotions folder. A misleading subject line also breaches the spirit, and in some places the letter, of email marketing rules.

Follow-ups

Many replies come from follow-ups rather than the first email, so plan a short sequence. We usually send two or three emails in total, a few days apart. Each follow-up should add something new: a different angle, a useful resource or a simpler question. Avoid "just bumping this up" emails that add nothing. Stop as soon as someone replies or opts out.

Handling replies

A positive reply is perishable. The faster you respond, the more likely it becomes a meeting. Answer the question they asked, then offer two specific times rather than a vague "when suits you?" Treat objections as questions: "we already have a provider" might be an invitation to talk about what would make them switch. We aim to answer interested replies within 30 minutes in working hours for exactly this reason.

Testing and improving

Test one thing at a time: the opener, the problem framing or the ask. Judge variants on positive replies and booked meetings, not opens. Open tracking is unreliable and can harm deliverability. Before blaming the copy, check that the list is right and the email is landing in the inbox, using our lead list guide and deliverability checklist.
