Unipile
One API for LinkedIn, WhatsApp, email and calendars, billed per connected account and not per message.
Unipile is a messaging API. You connect accounts, LinkedIn, Gmail, Outlook, WhatsApp, Instagram, Telegram and the calendars behind them, and drive them all from one set of endpoints. Billing is per connected account per month, five euros in the eleven to fifty band, with a minimum of forty-nine euros covering up to ten accounts, and no per-request or per-message fee.
What it is for
- Put a LinkedIn inbox inside your own productRead and write messages from your own software, without writing and maintaining the integration or the session handling.
- Unify channels behind one interfaceEmail, LinkedIn, WhatsApp and calendars on the same endpoints, so a conversation view does not have to be assembled from four different SDKs.
- Make volume a technical question, not a billing oneUsage is unlimited on a connected account. Only the platform own limits apply, which means the cost model never argues with the product design.
What I measured
- Five euros per connected account per month in the eleven to fifty band, with a floor of forty-nine euros a month including up to ten accounts. Read 18 Sep 2026.
- An account is an account whatever the channel: three emails, two LinkedIn and six WhatsApp is billed as eleven. Gmail and Outlook count email and calendar as one.
- Seven day free trial, no card, and no commitment on their published terms.
What it is not for
- You want an interface. This is an API for whoever is building the interface.
- You connect two accounts and send ten messages a month. The forty-nine euro floor is the real entry price.
- You want the provider to carry the compliance for you. You connect accounts, so the limits of each platform are yours to respect.

Questions people ask
How is an account counted?
One connected account, whatever the channel. Their own example: three emails plus two LinkedIn plus six WhatsApp is eleven accounts.
Is there a per-message cost?
No. Usage is unlimited and only the underlying platform limits apply, which is the main reason to choose an API priced this way.
What is the real entry price?
Forty-nine euros a month. Below ten accounts you are paying the floor, not the per-account rate.
Do I need this if I already use an outreach tool?
Probably not. This is for the case where you are building the tool, not buying it.
