Cold email leads for B2B agencies. Built for the people who send.
Agency new-business is mostly cold outbound + referrals. And templated cold outbound has stopped working. Outbound-in-a-Box delivers 50–500 prospects with openers that name a specific client win, case study, or expansion move the recipient's company made. The kind of email that gets answered with "how did you find that?" instead of getting marked as promo.
Why this works better for agencies than databases-plus-templates
Agencies tend to sell to clients who themselves have a marketing or product story they're proud of. That cuts both ways: easy to find a real signal, but the prospect is hyper-attuned to whether you read it or grepped their LinkedIn for keywords.
- Recent case studies are the single best signal. If a prospect published a case study about cutting CAC by 40%, an opener that references the specific work + ties it to a gap in your service is the highest-conversion move you can make. We surface these per-prospect.
- You're competing with other agencies, not with tool-sellers. The bar isn't "did you mention my company name". It's "did you do work I couldn't have done for myself." Signal-grounded openers clear that bar.
- Your tier rotation is small. A solo agency has a TAM of 500–2000 right-fit prospects total. You can't afford to spam them. But a 50-prospect signal-grounded batch every two weeks puts you at the top of inbox without exhausting the list.
The signal types we use for agency outbound
| Signal | Why it works for agency pitches |
|---|---|
| Recent client win / new logo | Prospect landed a marquee customer. Opener references it + ties to a likely follow-on need (e.g. expanded inbound, more content, brand refresh). |
| Published case study | The case study itself reveals what the prospect cares about + what they think is working. Highest-trust signal for agency-to-agency-style pitches. |
| Rebrand / website refresh | Means they're investing in marketing identity right now. Useful for design/brand/content agencies pitching adjacent services. |
| New service / vertical announcement | Prospect expanded their offering. There's likely a GTM gap as they figure out the new motion. Cite the announcement + offer the gap. |
| Hire of a marketing/growth lead | New leadership tends to bring agency budget with them. Cite the hire by name + their last 1–2 employers as a tell of what they'll prioritize. |
| Conference talk / podcast appearance | Cite specifically. Proves you watched/listened. Works especially well if the topic overlaps with your agency's specialty. |
Example openers we've shipped for agency clients
How to start
Two paths, depending on how convinced you are already:
- Convinced: Buy Starter ($97 / 50 prospects) and ship within 24h. Refund-if-templated guarantee covers you if any opener reads canned.
- Want to see quality first: Request a free 25-prospect sample. Same engine, smaller batch, 24h delivery, no card.
- Need one tiny ops workflow fixed first: Reserve a $1 micro-automation slot for a client CSV cleanup, delivery tracker, scrape manifest, QA checklist, or handoff file. The $1 reserve is credited toward the first scoped fixed-price build.
Most agencies start with a 50-prospect Starter, run the batch over 7–10 days, then graduate to a 250-prospect Growth pull or the $497/mo Retainer for steady pipeline.
One small caveat
If your agency's average deal size is under $2k, the math on done-for-you prospect lists is tighter. You need a high reply rate AND a high close rate to make $97/50-prospect pay back. We're a better fit for agencies with $5k+ engagements (consulting, retainer, build-out) where one closed client pays back ~50 batches.
