What can suppliers do within the RFP notification email?

When suppliers receive an RFP (Request for Proposal) notification email, they have the capability to mark it as in progress. This feature allows them to indicate that they are actively working on their response to the RFP, which can help both the suppliers and event organizers track the status of the proposals. Marking the RFP as in progress is particularly useful for accountability and time management, ensuring that suppliers are aware of deadlines and can prioritize their submissions accordingly.

The other options, while potentially beneficial for suppliers, do not typically align with the direct functionalities available through an RFP notification email. Submitting alternate proposals, contacting the event organizer, and requesting deadline extensions may involve different processes or platforms beyond the simple acknowledgment of an RFP's status. Thus, marking it as in progress represents a straightforward action directly linked to the management of the RFP process.
