One of the largest
senders in commercial email
You're sitting on a goldmine you're afraid to touch.
You paid to acquire every one of them. Then they went quiet, and you stopped mailing because one bad send can wreck your sender reputation. So the revenue sits there while new customers get more expensive every year.
Every record gets an answer.

Every record comes back sorted. Reactivate, warm, suppress, or reach them somewhere else.
Your dormant list, fully mapped.
Most tools hand back the winners and quietly delete the rest. We score every record and give you all of it, because knowing who not to mail is worth as much as knowing who to mail.
Reactivate Now
25%
Valid, recently active, strong fit and intent, low complaint risk.
Mail them now.
Warm First
15%
Valid, some activity, moderate fit and intent.
Nurture with lower-risk content first.
Suppress, Still Valuable
15%
Risky or stale for email, but the person still has value.
Reach them on paid, SMS, or direct mail.
Do Not Mail
35%
Invalid, toxic, spam-trap risk, or high complaint risk.
Suppress immediately.
Needs More Data
10%
Not enough signal to call it.
Hold, enrich, or test cautiously.
Gmail, Yahoo, and now Outlook cut off bulk senders above a 0.3% complaint rate. One bad send can put you there. Do Not Mail is your insurance.

The verdict, in plain terms
- Reactivate Now. Valid, recently active, strong fit and intent, low complaint risk. Mail them now.
- Warm First. Valid with some activity and moderate intent. Nurture with lower-risk content before a full send.
- Suppress, Still Valuable. Risky or stale for email, but the person still has value. Reach them on paid, SMS, or direct mail.
- Do Not Mail. Invalid, toxic, spam-trap risk, or high complaint risk. Suppress immediately.
- Needs More Data. Not enough signal to call it. Hold, enrich, or test cautiously.
The signals behind every call
- Deliverability. Bounce, catch-all, spam trap, seed account, and bot detection flag the addresses that put your sender reputation at risk.
- Complaint risk. Prior complainers and escalated screamers are caught before they cost you an inbox provider relationship.
- Activity and fit. Recent, category-relevant web activity separates people who will engage from addresses that are merely valid.
- Enrichment, per audience. Requested appends like credit tier, household income, homeownership, investor, and category intent come back on the same row.
The full file comes back on your first 10,000 credits, free. Every record scored, sorted, and explained. No credit card.
Get StartedIllustrative sample. Emails are masked and the data shown is fabricated for demonstration. Your real results are private to you.
We judge the person, not just the address.
Validators check whether an address is real. SafeReact answers the question that pays. Will the person behind it engage, safely? Every record is scored on thousands of signals across four stages.
Your dormant list
Your action map
Reachable
The address is live and won't bounce, so your sender reputation stays protected.
- Valid, invalid, catch-all
- Toxic and spam-trap risk
- Disposable and role addresses
Responsive
The person actually opens and clicks email. They're active, not just valid.
- Opens and clicks
- Web activity
- 30, 60, 90 day windows
Relevant
Our first-party data matches them to your product and category. They care about what you sell.
- Demographic fit
- Category interest
- Passive and active intent
Ready
Our models score who's primed to convert now and unlikely to complain. Good candidates, not spam-clickers.
- Predicted response
- Complaint risk
- Behavior model score
Reachable and Responsive are table stakes. Relevant and Ready come from a decade of real first-party data no one else has. That is the moat.
We send billions of emails a month. This is what we learned.
A decade of billions of emails a month across our own brands taught us what people actually engage with. Everyone else models it from fragmented third-party data. We watched it happen.
Everyone else
modeled, third-party data
SafeReact
real first-party data
They perform like your active list.
A Reactivate Now subscriber is not “inactive”. Your CRM only knows whether they opened your email, so the moment they went quiet it filed them under unengaged. It cannot see that they are active all over the web right now. SafeReact can, and we think they are ripe to re-engage with you.
How your CRM has them
Filed away. Most tools say delete this address.

Validators and list cleaners
They answer
Will this address bounce?
We answer
Should you mail this person, and if not, what should you do instead?
Data and enrichment providers

We answer
What should you do next with this contact?
Outcome-priced reactivation
They answer
They charge you per record they decide to call reactivated.
We answer
One flat rate per record scored. You know the price up front and you get the whole map, including who not to mail.
Not a cleaner. Not a data vendor. A decision.
More than reactivation.
Buy credits. Spend them when you're ready.
Buy the credits you need and use them whenever you're ready. One credit scores one record, and your credits stay good for 12 months from the day you buy them.
Your first 10,000 credits are free. The full scan, the full action map, not a sample.
You already paid for these people once.
A 50,000 credit pack is $1,000. In a typical dormant list about a quarter come back safe to mail, which puts the cost of finding them near 8 cents each. A brand new customer costs $50 to $200 to acquire. These people already know you.
Every record comes back scored and segmented. Including the ones you should not mail.
Your data stays yours.
We score it, hand back the answer, then delete it. We never mail your list, never hold your data, and never sell or share it.
