We link to wherever the issuer prefers to receive proposals. The options include a URL, email, or directly on Prosal.
For example, if you click on “Respond to Prosal” and it opens in email, it’s because the issuer chose to receive it via email and there is likely an email in the RFP or that opened in your Gmail the issuer would like to receive it.
We encourage you to review the RFP closely to find details about how to respond to an RFP.
