After a long time, the trend of postcard printing once again knocked on the door of printing industry. Once again, people are very devoted to selecting some beautifully designed postcards for their loved ones and sending them out as symbols of love and care. Looking at a postcard always reminds us that collecting postcards was also a hobby 20 years ago. Besides, people used to collect stamps on envelopes. It's a wonderful feeling to receive the mail delivered to your mailbox. Open it with great curiosity and enjoy the feeling. What color do you think of when you think of the mail received through the express service? Yes, that's right! Traditional combination of red and blue. With all these blue and red combinations of emotion in mind, I want to design a mail iOS icon template that will reflect some of your old memories as well as the emotion and warmth of postcards received through the mail service. Download and add this distinctive email iOS icon to your application design.
