Cold Email Outreach, Built Into Your UK Lead Tool
Cold email software for UK teams that lives in the same place you build the list. Connect a mailbox, let the AI draft your sequence, run A/B variants, warm up automatically, and read replies without a single CSV export.
Watch: An email worth replying to
Cold email software for UK businesses lets you send personalised, multi-step email sequences to a list of prospects from your own connected mailbox, then track what happens. The difference with Leadistry is that the emails are the last step of the same Pipeline that found the list. A company you find on the Companies House register goes from search result to live sequence with no export, no re-import and no data going stale in between. Your free trial sends its first 25 emails from your own mailbox, and uncapped sending is included on every paid plan from £29 a month.
Here is why running cold email in the place you build the list matters, and exactly what the engine does.
Why run cold email in the same place you build the list?
The standard UK workflow is a mess of moving parts. Pull a list from a data provider. Clean it in a spreadsheet. Run it through a verifier. Upload the CSV to a separate cold-email tool. Map the fields. Hope nothing broke. Then start writing. Every handoff is a place for data to rot and mistakes to creep in.
When the list and the outreach live in one pipeline, that whole chain collapses:
- Enrichment is already done. Every delivered lead arrives with the director's name, a verified website and a verified business email, extracted from the company's own site and checked before delivery. 1 credit = 1 lead, and a lead we cannot verify never ships and never charges.
- No re-import lag. The gap between building a list and contacting it is where deliverability dies. Here the record you found is the record you send to.
- Suppression is enforced end to end. Your do-not-contact list is checked at enrolment and again at send time. A director who asked to be removed cannot slip back in through a stale CSV.
- Signals feed straight into sequences. A new incorporation or an accounts-due trigger lands in your pipeline the day it appears, already enriched, and walks your approved sequence.
If you are still exporting to a separate tool, you are paying for two products and stitching them together by hand.
What is a cold email sequence?
A cold email sequence is a series of emails sent to a prospect over time until they reply or the sequence ends. Instead of one email that gets buried, you send a first message, then a follow-up a few days later, each from your real mailbox during UK business hours. Most UK B2B replies come from the second or third touch, not the first. That is why a sequence beats a single blast.
In Leadistry, the sequence is simply the email steps of a pipeline, running against leads the same pipeline found and verified.

How the outreach engine works
Setting up takes a few minutes:
- Connect a mailbox. Link a Microsoft 365 or Google mailbox. You send from your own domain, not a shared IP. That is what keeps you out of spam folders.
- Warm-up is automatic. The engine ramps your daily volume gradually rather than blasting from cold, so mailbox providers learn to trust the domain. The full ramp is in the warm-up guide.
- Let the AI draft the sequence. Your AI lead-gen employee reads your website and drafts the intro and the chaser in your voice. Drafts only. Nothing sends until you say so. Prefer to write your own? Saved templates and the starter gallery both work.
- Add A/B variants. Write up to three variants per step. Each prospect is randomly assigned one lane, so you get a clean read on which subject line actually wins. See A/B testing cold email.
- Set the sending window. Sending is capped to UK business hours, so your emails land when people are at their desks, not at 3am.
- Watch the replies. A reply stops that lead's sequence instantly and lands in a classified inbox. Bounces and unsubscribes are handled automatically.
Honest numbers, not vanity numbers
The analytics tell the truth, in this order:
- Replies lead. A reply is the one signal no scanner fakes, and the only metric that correlates with revenue.
- Opens are approximate. Security scanners fetch tracking pixels, so raw open counts flatter everyone. We filter known scanners, and still treat opens as a comparator between variants, not gospel.
- Delivered = sent minus bounced. No creative accounting.
The full story is in tracking that tells the truth. Before you send at volume, check your domain with the free SPF/DKIM/DMARC checker and any address with the free email verifier.
A note on compliance
There are no phone numbers anywhere in Leadistry, on purpose: UK PECR forbids unsolicited marketing calls on that basis, so we never sell them. Cold email to an incorporated business runs on a documented UK GDPR legitimate-interest basis with a completed ICO LIA. There is a public data-removal form honoured within 24 hours, plus director and company suppression lists enforced at enrolment and at send. The full picture is in the UK B2B data GDPR compliance guide.
Frequently asked questions
Which plan includes cold email outreach?
Every plan sends, including the free trial. Your 25 free leads can go into a pipeline and receive their first 25 emails, follow-ups included, from your own connected mailbox. Sending past those 25, plus saved templates, the full analytics and CSV export, is included on every paid plan, starting with Growth at £29 a month for 900 leads. Enrichment, Signals and integrations are on every plan. See pricing for the full breakdown.
Do I send from my own email address?
Yes. You connect a Microsoft 365 or Google mailbox and send from your own domain, with automatic warm-up and UK business-hours windows. Sending from your real domain, rather than a shared provider IP, is what protects your deliverability.
Can I A/B test my emails?
Yes. Up to three variants per step, with each prospect randomly assigned one lane. The per-step comparison shows which subject line or opener actually gets more replies.
How is this different from a standalone cold email tool?
A standalone tool needs a list imported into it. Here the emails are the last step of the pipeline that built the list: enriched, verified and suppressed in the same product, with nothing going stale in a CSV. Start a free trial with 25 leads, or add the Chrome extension to capture a UK company and its director from any site you visit. The trial sends too, and send 25 cold emails free walks the whole loop end to end before you pay anything.
