Check your email and eBay messages daily. As a new seller, it's important to get into the routine of checking your email and eBay messages every day. It's a good habit to get into and one that may be profitable as well. If you have fixed price listings with the make an offer, best offer feature potential buyers may be sending you offers. If you don't check your eBay messages, you may miss out on sales that will make you money. If you get questions about your products, potential buyers need to hear back from you so they can make fully informed decisions based on your answers.
Maybe they need a little more info or would like to see another angle of an item in a photograph? Checking your messages on eBay daily, makes the customer feel like you care and are running a good operation on eBay. Sometimes I get messages about an item that was shipped. For example, I sold three dolls to the same buyer last week. She contacted me and asked if I was planning to ship quickly because she was leaving for out of town. I responded that I would ship right away.
She had a friend pick up her mail and saw the delivery confirmation number posted on the eBay order page. And it showed it was delivered. The buyers question for me was had I sent in one box for each doll or were there three dolls in one single package. I wrote her back so she wouldn't worry that all three were safely packaged together. She said that was good news and her vacation would continue without having to worry About her eBay order. Occasionally a buyer has a change of address, or other shipping info or requests in an eBay message.
Without checking at least once a day, you might miss those important messages to keep your selling smooth sailing. If you get an email from eBay, that same message will also be in the my message area of eBay. That's one way you know it's the real deal and not spam or phishing. Never click on a link from an email you aren't certain is from eBay. It's a way for the scammers to try and collect information about you. The same advice goes for emails from PayPal.
Check the return address on the email to see if it's legitimate or not. If the address looks suspicious for that whole email to spoof@paypal.com, or spoof@ebay.com. Both addresses can help those infrequent but occasional spammers get caught. The last but most important reason to check your email from eBay and your overall eBay account daily is to see what items have sold and what items have been paid for. So you can get your packages ready for shipping. I like to ship first thing in the morning and then do my listings following that.
If orders come in during the day, I will ship right away as they pay with PayPal if I happen to be online. Remember, it can be profitable to check your email and you Messages daily.
