Do not put "Please help me with super easy shop!!!!!" or "Get paid to eat candy!!!! Super easy shop!!" I automatically delete those.
Riki isn't saying to personalize the mass emails, but to configure them so they are more useful to the shopper.
I've been getting several a day from the same company that say Big bonus added or something like that in the subject line. The body of the email is the same email as always about the shop and there is no mention of how much the bonus will be or even that there really is one. Today it said the bonus was the most they have ever offered. In my market that might be 50 Cents. This is a job definitely not worth doing at the base rate. I did tell the scheduler when they called the other day to let me know if they put on a big bonus. No I am not going to send an email to find out. Just tell me what the huge bonus is when you send the email and I will decide if I want the job. Very frustrating for shoppers. I do not think the bonus was negotiable.
My first move on emails is to check the locations. I don't waste the time to read anything in the email if the location isn't in my shopping circle. If not, I delete and move on.
