Sequential ad campaigns that follow your readers
Ad Journeys let you run multi-step ad sequences across newsletter audiences. Each step delivers a different message to subscribers who already saw the last one — building familiarity, trust, and conversion without any opt-in.
Tell a story across sends — without opt-in
Traditional newsletter ads treat every reader the same on every send. Ad Journeys change that. When a subscriber receives Step 1, they become eligible for Step 2 after a wait period you define. On the next relevant send, MailAdx automatically serves the next chapter of your story. No list upload required, no ESP integration changes, no subscriber action needed. MailAdx handles the sequencing entirely within the open-time serving layer.
- 2–5 step sequences with per-step native creatives
- Configurable wait periods between steps (days)
- Automatic eligibility tracking by email hash

Higher intent at every step
Subscribers who see Step 2 of your journey are not a random audience — they're readers who already received Step 1. They've been exposed to your brand once and are more likely to engage with a deeper message. Step 3 reaches subscribers who've had two exposures. By the time you make a direct conversion offer in the final step, you're talking to the warmest audience available in the newsletter channel. Advertisers using Ad Journeys typically see 2–4× higher conversion rates on Step 3 compared to standalone campaigns.
- Each step reaches a higher-intent subset of readers
- Awareness → Consideration → Conversion message sequencing
- Per-step CTR and funnel drop-off visible in real time

Everything you need
All the features, none of the complexity.
2 to 5 sequential steps
Design a journey from awareness to conversion — each step with a different creative, different message, different intent level.
Configurable wait periods
Set a minimum number of days between steps. Subscribers advance automatically once eligible.
Native format creatives
Each step uses a native ad with headline, body, thumbnail, and CTA — contextually embedded in the newsletter.
No opt-in required
MailAdx tracks eligibility by privacy-preserving email hash. Subscribers never need to join a separate list.
Pay per impression served
Billed only for the step that actually delivers. Subscribers who skip a send don't cost you anything.
Per-step analytics
Track impressions, clicks, and spend per step. See funnel progression: how many subscribers advance from Step 1 to Step 3.
“We ran a three-step journey for a SaaS product launch. Step 3 conversion rate was 4× higher than our standard single-ad campaigns. Readers who'd seen all three steps were already sold.”
