Just 1 in 4 are confirming for you??

That's extremely low. There's a lot more at play there than just the niche.

I see the opposite of that. 1 in 4 are not confirming. But that still means 20% - 25% lead loss. And the 20-33% attrition is typical in the IM space.

But, as per the post, the balance of having higher deliverability and being "spam complaint proof" is well worth the trade-off.

I just feel that by making tweaks, even more of the leads can be persuaded to double opt.
