Bulk text, sms and e-mail marketing help needed

I am in need of a freelancer who can assist me with bulk text, SMS, and email marketing for both existing and prospective customers. The ideal candidate should be knowledgeable in both SMS and email marketing platforms, as I would like to utilize both. I would like to send out marketing messages on a daily or weekly basis, so the candidate should be able to handle that frequency. Experience in creating engaging content for marketing campaigns is a plus, but just as important is having a platform that can send and reach customers and not get blocked or filtered.
