AnnexCore provided me with outstanding service with a very fast turn time! Highly recommended for sure!
AnnexCore has a broad experience with e-mail marketing and Mailchimp in particular. They managed to understand our needs easily, and define the best solutions in a timely manner. If you need experts in this field, there is no one else to call. Thanks again.
Fantastic service. Solved urgent problems we had inherited from others. AnnexCore jumped right in with almost no notice and knocked it out of the park, repeatedly. Very grateful. Thank you!
AnnexCore has been fantastic to work with! They provide fast and detailed customer service, and the work and updates they've done to our company's web and mobile site has been stellar (and fast)!
Awesome response and to the point. No wasted motion and solid help when I really needed it!!!
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
Great detailed work building a template that matched our site design and offered many features and drop and drag Mailchimp functions to make it easy to produce high quality newsletters.
