How do you deal with a cold email campaign that has high bounce rates?

When you see high bounce rates, the first thing to do is verify your email list. Depending on how you generated the list, you can use third‑party verification tools such as MailerCheck, ZeroBounce, or similar services that give you a deliverability score. Set a minimum threshold—if a contact falls below it, don’t send to them. Proper verification can eliminate roughly 50 % of bounces. I have free credits through Maker School and other deals, so you don’t have to pay a lot. My typical process is to send a small test batch of 1‑2 k emails to identify which niches or copy combinations perform poorly, then verify the good ones and scale the campaign. This way you only pay for verified emails that are likely to convert.

How do you handle high bounce rates in cold email campaigns—do you use an email verification tool?

I use several email verification tools, but I don’t rely on them exclusively. Deliverability isn’t black‑and‑white; it’s a gradient where strong copy can offset a higher bounce rate. When I launch a campaign I prioritize volume and strong copy over upfront verification—great copy pushes results forward, while invalid emails pull them back. I also weigh the trade‑off of including links (which hurt deliverability) against adding customized assets that provide value; the latter often outweighs the former, which is why I recommend asset‑based outreach combined with strong copy. For high bounce‑rate pauses, I simply turn off strict verification and accept a higher bounce rate because my copy is strong enough to balance it. This isn’t optimal, but I favor speed and agility—getting campaigns live quickly—then later add validation (e.g., Mails.so, NeverBounce) once the offer is proven. Maker School offers 250,000 free verification credits for completing an application, which is worth checking out.

I started a cold email campaign 10 days ago; initially it was booming, but then replies dropped and I got a warning about excessive bounces. Should I pause the campaign? What could be causing the dips in replies?

The reason your campaign started strong then declined is that your deliverability decreased over time. When deliverability drops, fewer emails reach inboxes, more get marked as spam, which further hurts deliverability—a negative feedback loop. This usually happens because either your email copy is poor, causing recipients to mark you as spam, or you're sending to a low‑quality list. To fix it, improve your copy and clean your list. Many people use email validation tools like mails.so to check DNS records and get a deliverability score; you can set a cutoff (e.g., only send if >50% deliverable) to automatically remove bad addresses. This cuts out bounces and boosts deliverability and campaign health, though it adds cost (you pay for the validation service), takes extra time to set up, and reduces your lead pool—often to about 30% of the original list after validation. So you trade some volume for better quality and fewer bounces.

Do you think this branded‑game cold‑email business idea is viable, and who would be the ideal customer profile (ICP) and what outreach angle should I take?

You're hitting a classic validation snag. You built a cool branded‑game cold‑email system, scraped 10,000 leads, got one lukewarm reply and no calls. The first step is to validate outreach before pouring more time into the product. Use a solid template, personalize each email intelligently, and send a high volume (500‑600 per day). Iterate on copy, test different niches and game concepts, and commit to a 30‑day run. Most failures happen because people quit before the feedback loop produces results. As for the ICP, look for brands that already invest in email marketing and have a sizable list they want to re‑engage – they’re the sweet spot for a branded‑game add‑on. Tailor your angle to show how the game can boost engagement and list growth for those brands.

Why don't you verify your email lists, and do you think poor copywriting is causing low open rates?

I don’t verify the first email blast because I’m confident in my copywriting enough to tolerate a higher bounce rate; verification is a trade‑off—better copy reduces spam complaints, so you can accept more bounces. I typically run a quick, unverified campaign to test a market, and if it works I double down and then pay for verification.
