Has anyone here had success running affiliate campaigns through email?

I recently started testing email outreach for an affiliate campaign, and I wasn’t sure what to expect. I’ve mostly relied on social and content marketing in the past, but I figured email could be a solid channel if done right.

At first, it felt like a slow burn - low response rates, lots of unsubscribes. But after tweaking the targeting, I started seeing better results. My last campaign actually led to a few conversions, which was a nice win.

For context, here’s my emailing stack:

• WarpLeads – unlimited export leads
• Reoon – email verifier
• Mailforge – email infrastructure
• Salesforge – email sender

Now I’m wondering, how scalable is this? Has anyone here had success running affiliate campaigns through email? What strategies worked best for you?
