500 Internal Server Error with Instantly

I cut my agency's tech stack from 50 tools to 20. Revenue went from $200K to $800K/month. Three years ago I was paying A LOT of money for software I barely used. I did a brutal audit: Does this generate revenue or deliver client results? If no → cancelled immediately. My lean 20-tool stack: - Cold email infrastructure keeping us out of spam. - Lead generation finding qualified prospects at scale. - Automation connecting everything without breaking. - LinkedIn running on complete autopilot. - Team operations costing pennies on the dollar. Every tool either fills our pipeline, closes deals, or delivers for clients. Everything else is dead weight. Comment “TOOLS” for my full stack + discount codes 💰

Hey everyone 👋 I've been meaning to share this with the community for a while now, and I figured it's time to stop gatekeeping this resource. Quick context: When I scaled our PR agency to $800K/month, one of the biggest operational costs was email infrastructure. At $8/mailbox on Google Workspace, running 300+ mailboxes was costing us $2,400/month just in mailbox fees. The alternative I found: There's a category of SMTP services with unmanaged IP addresses that cost $1-1.50 per mailbox/month. I'm currently running 375 active mailboxes across 75 domains through one of these services. What you get: • Unlimited scaling potential • 3-click setup process • Direct export into Instantly • Professional SMTP infrastructure • Full domain ownership and control The important caveat (please read): This is NOT for beginners. Here's why: With Google/Microsoft, they manage IP reputation for you. With these SMTP services, YOU are responsible for maintaining sender reputation. If you get spam complaints or hit spam traps, the entire IP range gets flagged and all your mailboxes go to spam. Who this is for: ✅ You already have a profitable cold email system with Google/Microsoft ✅ You consistently get low spam complaint rates ✅ You understand deliverability fundamentals ✅ You're ready to scale and reduce operational costs My current setup: I use this service alongside Google and Microsoft mailboxes to diversify infrastructure. When Google had those recent policy changes, my campaigns kept running because I wasn't 100% dependent on them. To get instant access to this: Comment "INBOX" below and I'll DM you the link 📦

What are you all using to source leads/emails? Apollo is closing down on all suppliers....

Hey everyone! I run a lead generation agency using cold email, and I wanted to ask something about Clay AI. Do I need to pay one monthly subscription and can then use it for all my clients, or do I have to pay a separate subscription for each client that uses the service? Basically, I just want to understand how the billing works if I manage multiple clients under my agency. Thanks!
