Saves a lot of time and repeated explanation. And you're building a system. Many internet surfers don't have the latest equipment or software. Simple systems, little details, and effective quality control will make a difference to your bottom line. Now and in the future.
Excellence flows from doing little things well, consistently.
For example, you can encourage donors to self-identify by inserting a gift planning reply card with every tax receipt. Repeat, every tax receipt. All the time. Contrast a consistent organization with one that isn't as consistent, isn't as systematic, and isn't bending over backwards to be responsive. Non-systematic organizations will insert reply cards for six months or a year and then quit.
