Co-Registrations - The biggest / Best Network?

[hellier]

Hello.

Does anyone use or have any advice on the best / biggest co-registration network? We are currently using one, which has reached it's daily limit of approximately 3,000 - 5,000 co-registration email addresses referred to us, of which we receive an approximate signup conversion of around 3% / 120 signups a day.

We are currently paying $0.015 (one and half cents) for 100,000 co-registrations a month.

We are relatively happy with this, but are looking expand our daily co-registrations on a grander scale.

If anyone has any advice / experience, it would be greatly appreciated.

Thanks

Have the sign ups been "quality" - turned into customers?

Yes. Although the conversions are as low as 1% at times, this has proved to be cost effective for us.
