I’m setting up my proxy for the first time and I want to make sure it’s legit before I commit to a full campaign. I’ve read about people getting burned by bad proxies—they think everything’s working, send 500 messages, then LinkedIn blocks half their account.
I grabbed a proxy from [provider], and I’m wondering: what’s the smallest test I can run to actually validate that this thing is working and won’t tank my account? Should I send 5 messages? 20? 50? And should I test it with personalized messages or is generic templating fine for validation?
I want to be confident without wasting my credibility with early recipients.
This is smart thinking. Here’s my validation framework: send exactly 10-15 personalized messages through the proxy to people you’d actually want to connect with. Not randoms, not a test list—real, relevant prospects.
Why personalized? Because if the proxy fails silently (which is the real worry), you want to catch it with messages that might actually get replies anyway. If all 10 go through and hit inboxes smoothly, your proxy is solid.
Watch for two things: (1) Are the messages sending without errors? (2) Are any of them getting bounced back or not delivering? If you get a 100% delivery rate on those 10-15, you’re good to scale.
Don’t test with generic messages because you won’t know if it’s the proxy or your message quality. And definitely don’t test with 50+ messages—that defeats the purpose. You want a micro-sample from a real warm-up perspective.
One more critical point: test from the same location and time you’ll typically be sending from. If you’re testing at 2 AM from your office and then sending campaigns at 9 AM from your home network, that inconsistency can actually be flagged. Keep your test conditions realistic to what your actual workflow looks like.
From a technical angle, if you’re tracking this properly, set up a webhook in LiSeller (if you have that feature enabled) that logs the proxy IP and response status for each message. That way you have hard data on whether messages are going through the proxy or getting rejected silently.
If you’re not using webhooks, at least manually check LiSeller’s logs or the platform’s message delivery status for those 10-15 test messages. Dead simple but catches issues before they become catastrophes.
Great question. LiSeller actually has a built-in proxy health check—have you looked at the dashboard settings? When you input your proxy details, the platform runs a quick validation to confirm it’s responding. But that’s just connectivity, not LinkedIn-specific validation.
For actual LinkedIn validation, you need the human test David described. Send a small batch, monitor delivery for 24-48 hours, and watch for any unusual LinkedIn notifications (like security alerts). If everything’s quiet and messages are landing, you’re golden.
Validation is about risk mitigation, not perfection. Send 12 personalized messages (enough to catch anomalies, not so many you’re burning prospects), wait 48 hours for read receipts and responses, then assess. If delivery looks clean and no LinkedIn warnings pop up, move forward confidently.
If even one message fails to send or you get a LinkedIn security alert, pause and investigate the proxy source. But if all 12 land cleanly? You’re validated. Move to 50 messages next batch, then scale from there.
I do the same test David mentioned but with a twist—I send to 10 people across different seniority levels and industries. That gives me confidence that the proxy works regardless of who I’m targeting. One test batch of all C-level execs might succeed for different reasons than a mixed batch.
After 48 hours of clean delivery, I’m confident enough to scale.
