Ihr Beitrag zur letzten Meile
Guten Tag Frau Lehmann,
Ihr Beitrag zum neuen Retourenlager in Bremen hat mich abgeholt. Besonders der Satz, dass die letzte Meile der Rückabwicklung noch Handarbeit ist.
Genau dafür hätte ich eine Idee. Hätten Sie kommende Woche 20 Minuten?
Pulled from her latest LinkedIn post. Written for her, not pasted at her.
Sends from your own mailbox, in your next sending window.
How it works
From cold name to booked meeting.
Drop in a prospect
Paste a LinkedIn URL or pull a contact from your CRM. PERSO builds the full picture of role, company and context in seconds.
Pick a play
Multi-touch sequences that react to what happens. Connection accepted? The DM goes out. No reply? The follow-up is already queued.
Approve in one click
Every message lands in your queue ready to send. Edit if you want, hit approve, and it goes out from your own mailbox.
Watch replies land
A reply stops the sequence on the spot and lands in your inbox. No prospect is ever chased after they answered.
Templates get ignored. PERSO gets answers.
Hyper-personalised is not a feature we bolted on. It is the name.
Trained on your wins
It learns from thousands of emails your team already sent, and which ones actually got replies. Your voice, your winning angles, at scale.
Written for one person, once
No merge tags, no variant pool. Every message is composed fresh for the one person it goes to, in the language they answer in.
Guardrails that scale with you
Daily limits, rejection cooldowns, company-wide contact ceilings and a suppression list that survives everything. Scale without burning your domain.
Integrations
Plugs into your stack.
Everyone on your team connects their own mailbox and their own LinkedIn. Mail goes out as them, and replies land where they already read them.
No CRM? No problem. PERSO keeps its own record of every prospect, touch and reply.
Built in Zürich
A European company for European sales teams. PERSO writes to your prospects in the language they answer in: German, French, Italian, English and more.
Your data stays in Europe
Application and database run in Frankfurt. Nothing is stored outside the EU.
GDPR by design
Opt-outs checked live before every touch. An erasure is honoured everywhere and cannot be re-imported.
Enrichment included
Addresses found and bounce-checked before anything sends. No list imports full of dead mail.
Measurement
No number it cannot stand behind.
A 100% reply rate from two emails is noise, and a tool that prints it will be believed. Every rate in PERSO arrives with the count behind it, and the ones too small to trust show a dash instead of a guess.
Four sends is not a rate. It stays a dash until it means something.
Why I built this.
I sell for a living. Well over a thousand first emails to finance and operations teams, in German, French and English. PERSO is built on the ones that got answered, so it writes the way I do, and it never sends anything I have not read.
