This comparison explains what Waalaxy and murmur do, how their channels differ, and when to choose one, the other or both. Both serve B2B prospecting, but they take different routes: Waalaxy writes to people on LinkedIn, then by email; murmur writes to businesses, through the contact form on their website.
This page is published by murmur. The information about Waalaxy comes from its website, read on 26 October 2026, and may have changed since.
What is Waalaxy?
Waalaxy describes itself as “the perfect tool for LinkedIn outreach”, with the headline “Make LinkedIn your #1 acquisition channel”. According to its website:
- Channels: LinkedIn first, with email alongside: the site says it is “made for LinkedIn + email outreach”, with automated invitations, messages and follow-ups.
- AI: a writing assistant for messages (described on the French site as trained on Waalaxy’s own methods) and an analysis of positive replies by campaign.
- Adoption: “200,000+ sales reps, founders, and teams worldwide” claimed; a 4.8/5 rating across more than 2,000 reviews (Chrome Web Store and G2).
- Entry price shown: the Pro plan at €19 per user per month, with 300 invitations a month; Advanced at €49 (800 invitations); Business at €69 (800 invitations, 500 email-finder credits, cold email sequences, LinkedIn + email campaigns). The page offers monthly, quarterly (−20%) or yearly (−50%) billing without saying which period the displayed prices correspond to. A 14-day free trial.
Waalaxy campaigns rely on the user’s LinkedIn account, and therefore on the limits LinkedIn sets. LinkedIn publishes no number of allowed invitations; beyond its limit, an account can be blocked from sending invitations for about a week, Premium included (LinkedIn Help).
What is murmur?
murmur (murmur.ad) is a French B2B prospecting platform that writes each target business a message personalised from its own website and submits it through the contact form that business publishes.
- Channel: the business’s website contact form. murmur does not run LinkedIn and sends no cold email.
- Data: a database of 44.1 million businesses in 164 countries, built from public sources, or your own list of websites.
- What you need to set up: a reply address. No LinkedIn account is involved.
- Price: 0.1 to 3 credits per contact, charged on proof of submission; the Starter plan is €89 excluding VAT for 300 credits a month. Your first 300 contacts are free, with no credit card.
- Scope: the self-service platform sends to France; the United Kingdom is next.

When should you choose Waalaxy, and when murmur?
Waalaxy is the better fit if your buyers are active on LinkedIn, if you want to reach a specific person by job title, and if you are happy to build the relationship on your own account, at the pace LinkedIn allows.
murmur is the better fit if your targets are small businesses, tradespeople or shops whose owner is rarely on LinkedIn, if you do not want to involve a personal account, and if you want to write to the business through the channel it published on its website.
Can you use Waalaxy and murmur together?
Yes. The two tools do not get in each other’s way, since they use different channels. A common split: murmur for the first contact with the business, Waalaxy for a named approach to its managers when they are on LinkedIn. Two precautions:
- Space out your contacts: a business reached through its form and on LinkedIn in the same week will notice.
- Honour requests to stop everywhere: a business that objects on one channel does not want to hear from you on the other. An objection received by murmur applies across all its clients (opt-out page).

No. murmur connects to no LinkedIn account. It submits your message through the business’s contact form, under your name and with your reply address.
How many businesses can I contact with murmur?
It depends on how many businesses in your target publish a form, on each country’s rules and on your credits. murmur shows the number of reachable businesses before you commit.
