Your list defines your deliverability.
We clean it before it burns.
We validate every address, remove bounces and duplicates, and flag cold contacts. Sending to a dirty list sinks your reputation: every bad send costs you the next one.
We verify your list against the real servers, remove invalid addresses, bounces and duplicates, and separate cold contacts for a double opt-in re-engagement. It's the first thing to do before any campaign: a dirty list sends you to spam.
What's included
- Real SMTP validation of every address
- Deduplication and normalization
- Removal of hard bounces and spam traps
- Flagging of cold contacts for re-engagement
Three steps, without you touching a thing.
You upload your list
You send us your list (CSV/Excel) securely.
We validate
We verify address by address and hand back the clean list + a report.
Re-engagement (optional)
For the cold ones, a double opt-in campaign compliant with Law 81.
Clear and separate.
Buying lists is not an option: besides being illegal under Law 81, it burns your domain. We clean what you already have and help you capture properly.
Who it's for: Anyone with an old, inherited or bounce-heavy list, before their first campaign with us.
Worth clarifying.
Can you sell me a contact list?
No. Buying or selling lists is illegal under Law 81 and ruins your reputation. We work on your own list and help you capture with consent.
