Dear Madame/Sir,
Guarantee the contest and you will get a lot more interest,
even with the minimum prize.

What does Payment Not Guaranteed mean for designers?

When a project is marked as guaranteed it means that the customer has committed to paying out a designer and has waived their right to get their money back. If it is not guaranteed, the customer can opt to get a refund of their money.

You can determine if a project is guaranteed by viewing the job brief and looking out for the following image marked on the project:
Customers are eligible for a refund if they have not selected to guarantee their project and in accordance with the DesignCrowd refund policy.

Dear Madame/Sir,
I have submitted my designs.
I know you are busy but would you mind to give me your feedback?
Please tell me if I am on the right track.
Thank you
Best regards,
Coco

Dear Sir,
After a lot of changes, could you guarantee the payment?

Thanks Coco, but I am not in the position to do that. I have had a number of designs and I have narrowed that down to 3 at the moment. Thanks for all your hard work. Do appreciate it.
