I'm constantly amazed at poor provider communication skills, not only given the direct impact of good, prompt communication to their cash flow, but given that sloppy communication can send a very negative message about a providers personality and professionalism. Some providers are quite good of course, but a lot fewer than you'd expect.
Yes, providers have differences about how they'd like to communicate, but don't always think through how to make those preferences work for us hobbyists. I never have a problem if things can't work out, but I absolutely hate wasting a lot of time pursuing a meeting that was never going to happen, and I hate feeling my time was wasted by a girl who couldn't be bother to reply to a voicemail/email/private message
--if you have strong preferences (prefer phone, prefer text) say this clearly in your ads.
--Don't mention any means of contact that you don't check on a very regular basis, and if any doubt, clearly tell people not to contact that way (I don't check email that often, my phone doesn't have texting
--try and make it as clear as possible whether you are generally/regularly available, or your ad is only for a specific window of opportunity. Hobbyists don't always make contact the same day, and its frustrating to get radio silence from someone who posted three ads in the last week
--if you use phone heavily, you must use voicemail (or clearly indicate in ads that you don't have voice mail, and provide an alternate means of contact if you don't immediately pick up). If you have voicemail, have some type of response that confirms we dialed the right number, and never, never let the message box get full.
--if you use email, consider some type of auto-response message so we'll know our message got through. And check the spam folder constantly.
--if you are down with the flu, or have gone to Vegas for three weeks, make sure you have a voicemail message or email auto-response that indicates you might not be responding right away. Websites are good for this type of general availability info, but if you don't have a website, do something to make sure your gentleman callers aren't totally ignored for days and weeks
--Mistakes happen. Things can slip through the cracks. If you suddenly find an eight day old voicemail/email, send a really apologetic reply. The guy's immediate interest may have passed, but the courtesy will be remembered.
--Worse shit can also happen. If your phone gets stolen, or you get kicked out of your apartment, or you are kidnapped by aliens, and you have to disappear for a while without any way to give notice, let regulars and others know once you are back on the grid. "hey, apologies to anyone who tried to contact me in the last couple weeks, but I'm back in town and things are slowly getting back to normal"
--I expect serious screening before any first visit, but I understand that a lot of guys are a bit dense about screening. A brief reminder about screening in ads may help alert the guys who are only partially dense. More detailed explanation of screening requirements on websites or via auto-response emails can be even more helpful. No hobbyist that you'd ever want as a regular will ever take the slighest offense at these reminders.
