Unipile - Outreach FAQ

Outreach Integration FAQ

Everything you need to know about adding multi-channel outreach capabilities to your platform

Unipile provides a unified API covering LinkedIn (Classic, Recruiter, Sales Navigator), Email (Gmail, Outlook, IMAP), WhatsApp, Telegram, and Instagram. Your users can send messages, invitations, InMails, and emails across all these channels from a single integration.
You build the sequence logic on your side, Unipile handles the execution. Your platform defines the steps (LinkedIn invitation, follow-up email, WhatsApp message), timing, and conditions. Unipile's API sends each action on behalf of your authenticated users, respecting platform rate limits and guidelines. When a prospect replies, webhooks notify your system in real time so you can pause or adjust the sequence.
Account protection is built in. Unipile includes proxy management, daily activity quotas, and warm-up tracking to help your users stay within platform guidelines. You can configure daily limits for LinkedIn invitations, messages, comments, and emails. The API uses respectful usage patterns aligned with each platform's policies, reducing the risk of restrictions.
Yes. Unipile's API lets you aggregate all incoming messages, whether from LinkedIn, Gmail, Outlook, WhatsApp, or other connected channels, into a single unified inbox within your application. You receive real-time webhooks for every new message, enabling you to build reply detection, sequence stop rules, and conversation threading across all channels.
If you've already integrated a messaging provider, you can add outreach capabilities in 1 to 2 days. From scratch, expect 4 to 10 days depending on your team. Our documentation covers every endpoint with code examples, and our support team is available via Slack and live chat during integration.
Yes. Each of your users can connect multiple accounts (LinkedIn, Gmail, Outlook, WhatsApp) through Unipile's hosted authentication flow. Your platform can then act on behalf of any connected account, enabling team-based outreach, account switching, and delegation, all from a single API integration.
Absolutely. Unipile's Calendar API connects Google Calendar and Outlook Calendar. You can programmatically create, update, or cancel meetings directly from your outreach platform. Combine it with reply detection to automatically trigger calendar invites when a prospect responds positively, no manual back-and-forth needed.
Yes. Unipile is GDPR compliant and SOC 2 certified. All data is processed securely with encryption in transit and at rest. We act as a technical intermediary on behalf of your authenticated users, meaning data flows through secure, auditable channels. Please contact us if you require audit reports or additional security documentation.
