How AgentSDR works

What you get instead of HeyReach

Multi-account LinkedIn

Several accounts, each held to its own limits

Choose which LinkedIn senders a campaign may use. Every account keeps its own daily limit, working hours and rest between runs, and one that hits a LinkedIn limit stops for the day while its leads go back to the queue.
  • Daily limit per account, with a warning past the safe edge
  • Small runs, 30 to 60 seconds apart, then a rest
  • A person already invited by an account is never invited again by it

Beyond LinkedIn

When they accept, they are already in your CRM

A LinkedIn reply reaches the same AI CRM as email and WhatsApp replies, classified and drafted. If someone answers on another channel, their LinkedIn follow-ups stop.
  • One record per person across channels
  • Replies classified into your categories
  • A personal campaign type keeps chosen replies out of the shared inbox
channels from one lead record: email, LinkedIn, WhatsApp

Being fair

Where HeyReach is the better choice

Open source is not the right answer for everyone. If one of these describes you, use the other tool.

  • LinkedIn is your whole motion

    HeyReach is built for LinkedIn at scale, with sender rotation, voice notes, conditional logic and agency plans. AgentSDR does LinkedIn well but also spreads effort across other channels.

  • You run an agency that needs white-label

    HeyReach offers white-label customisation on its agency plans. AgentSDR gives each client a separate organization but does not rebrand the app.

  • You need an API

    HeyReach lists API and webhook access on all tiers so you can automate around it. AgentSDR has no public API for that today.

  • You want someone else to operate it

    HeyReach is hosted and offers a done-for-you service. AgentSDR is yours to deploy and maintain.

Why teams switch

Reasons to move from HeyReach to AgentSDR

  • No fee per sender

    AgentSDR does not charge by LinkedIn account. You pay Unipile for the connections you use and nothing to us.

  • The follow-up is built in

    A reply on any channel lands in one AI queue, so LinkedIn conversations do not need a second tool.

  • Your accounts, your server

    Sign-in happens on Unipile's hosted page, so AgentSDR never sees a LinkedIn password, and the data stays in your database.

  • Conservative defaults

    30 invitations a day on premium, 5 on free, with settings that warn before you go past the safe edge.

FAQ

Questions, answered

Is there an open-source alternative to HeyReach?

AgentSDR is open source under AGPL-3.0 and sends LinkedIn campaigns from several accounts through Unipile. It also covers email and WhatsApp. It has no white-label option or public API.

Can AgentSDR use multiple LinkedIn accounts?

Yes. Connect each account through Unipile and choose which senders each campaign may use. Every account has its own daily limit and working hours.

What are the LinkedIn limits?

By default 30 invitations a day for Premium or Sales Navigator accounts and 5 for free accounts, in runs of 3 to 4 with 30 to 60 seconds between them. You can change all of these, and the settings warn before the risky range.

Is automating LinkedIn allowed?

LinkedIn's terms do not allow automation, and accounts can be restricted. AgentSDR's limits keep activity modest, but no tool can promise an account stays safe. Read the responsible use page before you start.

Does AgentSDR support voice notes or profile views?

Not as outreach steps. A sequence is a connection request, an acceptance message and up to three follow-ups. Profile lookups are used to match leads to their LinkedIn profile.

Can I use AgentSDR for client work as an agency?

Yes. Give each client its own organization on one deployment, so leads, accounts and settings stay separate.
