Letter M Marketing were excellent to work with! They were very supportive in working through challenges and pushing for a successful end product that was specific to our needs. They were extremely knowledgeable, professional and always willing to work with us. Written on behalf of the Municipal Staff from Meaford, Ontario.
Working with Doug and the team at Letter M for the past 3 years has been a wonderful experience for the ECNO team. They are very responsive to requests for support, and have assisted in developing our new Strategic Directions. The day-to-day communication and web site guidance has been excellent. Their ability to develop and promote our brand through various social media channels has been extraordinary. And, to quote the common word of the pandemic, they have been able to pivot and address needs that become priorities quickly. Highly recommend them!
The Letter M has been a critical strategic partner with Destination Marketing Guelph for the last year and a half. They have provided unparalleled guidance and support through brand development and all aspects of creating and executing a destination marketing organization and all that entails. Doug MacMillan and his team are an exemplary example of a local business that can deliver global impact through informed strategies, oversight and leadership.
