I have worked with AnnexCore on and off for several years. THEY ARE AMAZING and that is why I am a repeat customer! They make the whole process stress free and they are very professional. They set up and organized my mailchimp automation account and designed my whole newsletter. I am very happy with the work they did. THANK YOU ANNEX CORE!
Very quick turnaround on our MailChimp template and edits. Would definitely hire them again.
AnnexCore was fantastic to work with and produced an outstanding marketing campaign from start to finish. The service and response time was instrumental in completing our project on time considering our tight time frame. I will be collaborating in the future with AnnexCore and recommend them strongly.Pat M Red Capture
