Hello Sir,
I am interested in your project, as I have noticed that you are seeking for an email marketer to design you 3 emails with 3 different subjects and send 15 emails 5 for each project.
I have an experience in Mailchimp as I have done email campaigns before which produced excellent results. You are more than welcome to visit my profile and check this project.
I think that we need to discuss your project more and to discuss how I will handle your project, so we can set a contact appointment for this.
I appreciate your concern for reading my proposal and hope to hear from you soon
