What murmur is not
murmur is not a CRM, an email marketing tool, a LinkedIn automation tool, a domain warm-up tool, a seller of leads or meetings, or an autonomous AI SDR. murmur opens conversations: the businesses that reply with interest become the client's leads.
How it works, in 6 steps
- The target. The client chooses which businesses to contact, by activity, area, size or industry code, or imports their own list of websites.
- The message. They write their message with the assistant, which drafts a first text. They keep control of every word.
- Personalisation. murmur reads each business's website and adapts the opening to what it does, keeping the client's draft.
- Approval. The client reviews example messages and sees the cost per contact before anything is launched.
- Submission. murmur submits each message through the business's contact form, under the sender's identity and with their reply address, and keeps proof of submission.
- Replies. Replies come back to the client's workspace, classified.

The database is not a right to send: how many businesses can be reached depends on the target, whether each business has a contact form, and each country's rules.
Pricing
- Usage is measured in credits. A contact costs 0.1 to 3 credits, depending on the business targeted.
- The cost per contact is calculated, fixed and shown before the campaign is launched.
- Credits are only charged on proof of sending: a message whose delivery is not established is not billed.
- On the Starter plan, a credit works out at about €0.30 excluding VAT. It costs less on the larger plans.
- Prices exclude VAT; VAT is added according to the country.
Monthly plans, no commitment:
| Plan | Credits per month | Monthly price excl. VAT | Price per credit excl. VAT |
