Legal Marketing Agency: How to Choose the Right One in 2026
$250M+ managed Meta ad spend · 600+ plaintiff law firms · 100+ mass torts · 2M+ leads since 2015
A legal marketing agency runs a firm's advertising and client acquisition. For plaintiff and mass tort work, the right agency specializes in paid social, prices transparently, lets the firm own its data, and reports on signed cases — not clicks. MTAA is a legal marketing agency built only for plaintiff firms: $43.36 blended per lead, $60.39 per signed case, on cost-plus-15% pricing since 2015.
Five things to vet before you sign
1) Specialization — do they run your case types every day? 2) Pricing transparency — can you see the actual ad spend, or is it buried in a per-case price? 3) Data ownership — do you keep the ad account, pixel, and claimant data? 4) Intake — is qualification handled, and how fast? 5) Reporting — are you measured on signed cases or vanity metrics?
Red flags
Watch for lead resale (the same lead sold to several firms), inflated cost-per-case pricing that hides the real ad spend, long lock-in contracts, and "we'll onboard an intake partner later" when speed is what wins a hot tort. A plaintiff-specialist agency should already have optional intake.
How MTAA stacks up
The minimum campaign budget is $25,000, including all fees, with no fixed spending timeline. Pricing is actual Facebook and Instagram ad spend plus a 15% management fee, a one-time $1,000 setup fee per tort, and $100 per signed retainer when CloudIntake is used. The management fee is earned only as advertising money is spent. Unspent client funds can be refunded at any time for any reason, after accounting for fees already earned or owed.

Frequently asked questions
How much does a legal marketing agency cost?
It depends on the model. MTAA uses cost plus 15% on ad spend, currently delivering qualified leads at a blended $43.36 and signed cases at $60.39.
Should I hire a generalist or a specialist agency?
For mass tort and plaintiff PI, a specialist is usually worth it: case-type fluency, compliance posture, and realistic cost-per-case benchmarks a generalist won't have.
Who owns the leads and data?
With MTAA, your firm does — the ad account, pixel, creative, and claimant data are yours, with chain-of-custody on every lead.
Does a legal marketing agency handle intake?
Some do, most don't. MTAA includes CloudIntake — bilingual, criteria-driven screening with retainer execution — so leads are qualified, not just delivered.
