As your target audience will be professionals using email and communications I wanted to provide a logo that expressed communication as a whole, and my logo is simple (to show ease of use) but expresses communication, we used a font that I use to keep a professional but fresh element that would appeal to SMB’s. I think the logo shows your requirement of being reliable by using flat levels rather than shadows and complex lines. The single representation of a person but in a speech bubble is meant to show that ‘you are not alone, connect and communicate’. I have provided two colour options but the logo would work well in most colours and as a simple white-out image, and very easy to convert into an app image. I look forward to your feedback.
We are happy to finally see an alternative concept for the logo! I really like the fact that the logo is simple and can be converted to an app image - we have been thinking about this when ranking the logos.
