I got Wishlist Member through their earlier Appsumo deal. The trouble with WM is that new registration emails land in the spam folder.

The best solution I found was SMTP relay services costing $25 per month.

I've now found that Acumbamail offers an SMTP relay service as part of this lifetime deal.

It's a complete no-brainer because apart from the great price they'll do more to protect their sending reputation than a specialist SMTP company. Those companies sometimes have emails landing in the spam folder and very often have poor support.

I'm grateful to get this.
