Cold email and B2B outreach automation

I set up cold email outreach for UK firms that sell to other businesses: the sending domains, the authentication records, the prospect list, the sequence and the hand-off into your sales pipeline. The aim is a small number of well-chosen messages that land in the inbox and get answered by a person, not a blast that burns your domain in a fortnight. LinkedIn steps can sit inside the same sequence, but as reminders for you to act on, not as automated activity.

This page covers outbound prospecting to people who have not asked to hear from you. If you want automated emails to people who have signed up or bought from you, my email automation service is the closer fit. If the job is capturing and routing enquiries that arrive on their own, see lead generation automation.

Who this suits, and who it does not

Outreach automation works best for a consultancy, agency, software company, manufacturer or specialist supplier with a clear idea of who buys from them, a deal value high enough to justify one-to-one selling, and someone with time to answer replies. If you can describe your best customers by sector, size and job title, you have the start of an ideal customer profile, and that is what the list is built from.

It is a poor fit if your buyers are mostly sole traders or consumers, because the consent rules make cold email to them close to impossible. It also struggles when nobody owns the replies. A sequence that generates interested answers which sit unread for three days does more harm than no sequence at all. And if you want thousands of emails a week, I am the wrong person: that volume almost always ends in spam folders and complaints.

Deliverability comes before copy

When outreach gets no replies, the wording is rarely the first thing to check. Often the emails never reached the inbox. Email deliverability depends on whether the receiving server trusts the sender. Gmail, Google Workspace and Microsoft 365 judge that trust on authentication, sending history and how recipients react.

So I never send cold email from your main company domain. I set up one or two closely related domains for outreach, so that if something goes wrong your invoices, proposals and day-to-day mail are not affected. Each gets SPF, DKIM and a DMARC policy, a proper mailbox with a real person’s name, and a forwarding redirect to your main website. Then comes domain warming: a few weeks of low, gradually rising volume before any prospect receives a message.

I also keep each mailbox to a modest daily volume, measured in dozens rather than hundreds, and I usually switch off open tracking. Apple Mail Privacy Protection makes open figures unreliable, the tracking pixel can count against you with spam filters, and replies are the number that matters anyway.

What the work covers

The rules: PECR, UK GDPR and LinkedIn

Cold email to businesses is lawful in the UK when it is done properly, and it is easy to get wrong. Under PECR, unsolicited marketing email to a corporate subscriber such as a limited company or LLP does not need prior consent, provided you say who you are and give a working way to opt out. Sole traders and partnerships outside Scotland are treated as individual subscribers, so the consent rule applies to them. A quick check on Companies House tells you which is which.

UK GDPR still applies, because a named person’s work email address is personal data. In practice that means relying on legitimate interests, writing down a legitimate interests assessment before the list is built, telling people where you got their details no later than your first message, and honouring every objection immediately and permanently. The assessment and the short privacy wording are agreed with you before any list is built, and your own adviser should read anything you are unsure of.

LinkedIn’s User Agreement prohibits bots and other automated ways of sending messages, adding connections or copying profile data. Tools that do this put the account at risk of restriction, and the account is usually a senior person’s own profile. I do not build that kind of automation. Manual LinkedIn steps, prompted by the sequence, are both permitted and more convincing to the person receiving them.

How I run a build

1. Brief. We agree the customer profile, the offer, who answers replies and what counts as a good outcome.
2. Infrastructure. Domains, mailboxes and authentication go live, and warm-up starts. This runs alongside the next two steps.
3. List and compliance. I build and check the first list, and we sign off the legitimate interests assessment and privacy wording.
4. Sequence. Copy is written, reviewed by you and loaded with the LinkedIn tasks and CRM rules.
5. Pilot. A small first batch goes out. We read the replies together and adjust the copy, the list or both.
6. Handover. You get the documentation and a walkthrough. Any ongoing support is agreed in writing before work starts.

Problems I see most often on UK outreach

• Cold email sent from the main company domain, with no DMARC record, until ordinary client mail starts landing in junk.
• Bought lists full of old addresses, which produce bounces and spam traps in the first week.
• No record of where contacts came from and no assessment on file, which leaves the business exposed when someone complains to the ICO.
• Long, image-heavy emails with three links and an attachment, which look like marketing to both the filter and the reader.
• Unsubscribes honoured in the sending tool but not in the CRM, so the same person is emailed again by a colleague a month later.

What you receive

• Outreach domains and mailboxes, authenticated, warmed and owned by you.
• A sequencing tool account in your name, connected to your CRM.
• A first prospect list with the source of every record noted.
• The sequence copy, LinkedIn task steps and reply rules.
• A legitimate interests assessment and privacy wording to review with your adviser.
• A short written guide to sending limits, list hygiene and what to check each week.
