Your own London list of marketing agencies
Marketing agencies are often small teams led by founders who still win the clients, with larger agencies adding account and operations roles. They buy tools and white label services that let them deliver more work without hiring.
Working marketing agencies in London goes faster with one clean file for the city and a segment per neighbourhood or nearby town such as Kitchener, Hamilton and Mississauga. Status and tags show who is new, contacted or already a customer.
Most sellers work from a bought list that everyone else has too. A list of marketing agencies in London that you built yourself is the one nobody else is emailing yet.
Build your London list of marketing agencies in four steps
Nothing is written to your database until you confirm it.
Collect marketing agencies in London
Export marketing agencies in London from agency directories and review sites or Google Maps listings as CSV, or paste the results page into paste and collect.

Import into one lead file
Drop the file into a lead file called Marketing Agencies London. Columns are matched for you and duplicates are flagged before anything is saved.

Fill in the missing emails
No email in the export? Tick hello@, info@, studio@ and newbusiness@ and addresses are derived from each website.

Reach them in small batches
Pick the segment, keep only status New, write one mail with placeholders like {company|your team} and send it in small batches.

Fields worth recording for marketing agencies in London
Add these as fields in your lead file. Any column in your import can become a field.
| Field | Why it helps |
|---|---|
| Company name | The key field. Duplicates are checked on it or on the website. |
| Website | Needed to derive an email when the export has none. |
| Services | SEO, social, paid or branding agencies need different partners. |
| Team size | Shows capacity and whether they outsource. |
| Client sectors | Agencies focused on one sector may need specialist help. |
| White label | Whether they already resell outside work. |
| Founder | The decision maker in most small agencies. |
What slows down prospecting marketing agencies, and the fix

Directory lists include freelancers who call themselves agencies.
Add a team size field and filter on it before you send.
Partnerships take several conversations to close.
Statuses, notes and full history per contact keep the thread over weeks.
What to say to marketing agencies in London
Write one mail with placeholders and let the details change per record. These openings tend to work with marketing agencies.
- Offer capacity they can resell, framed as extra margin on work they already sell.
- Show work you did for a similar agency, since agencies judge on output.
- Keep the email itself well crafted, because agencies notice sloppy outreach instantly.

Read moreEmailing marketing agencies in Canada
In Canada, commercial email falls under Canada's Anti-Spam Legislation (CASL), which is stricter than most and generally requires express or implied consent before you send. Implied consent only applies in limited cases, for example when someone has conspicuously published their business email address without saying they do not want messages and your message is relevant to their role. Every message must identify you, include your contact details and offer an unsubscribe option that works. This is general information, not legal advice.
Tuesday to Thursday mornings tend to work best; Mondays are for planning and Fridays for delivery. Read the deliverability guide before your first send.
Questions people ask
Yes. Put London in its own segment, or keep a City field and save a filter such as city contains London. You always see which part of the market you already worked.
If your file has an email column, that wins. If it only has websites, tick the prefixes you want, such as hello@, info@, studio@ and newbusiness@, and Riftjaw derives addresses from each domain. Derived addresses are good guesses, not verified, so start with small batches.
Yes. The Free plan runs the whole pipeline on one list with small campaigns, and you do not need a credit card. Move to Pro when you want more lists, segments and bigger campaigns.
Segment agencies by the services they offer and send each segment a campaign about the service they could resell. Track replies with statuses and follow up on those who opened.
Yes. Agencies use it to build their own client prospect lists, and the Agency plan gives separate workspaces per client.
