Techniques for detecting errors in communications include generating a communication based on a received payload and an existing template that corresponds to the payload. An image file indicative of the visual appearance of the communication is generated. The visual appearance of the communication is compared to that of a model, which indicates an expected location, color, or shape associated with particular elements of the communication. If the visual appearance deviates from that of the model by at least a threshold tolerance, a notification indicative of a potential error in the payload or template may be generated. If the visual appearance significantly deviates from that of the model, transmission of the communication may be prevented.
