* Correct date and time on the QSL. One of the most common reasons why dates and times are incorrect is a failure to use UTC time and date.
* QSL Card Design. Callsigns should be on the same side of the QSL card as the contact information. This will assist the QSL Manager from having to constantly flip the card from back to front, thus eliminating the chance to get your callsign wrong.
* Pull & Seal Security Envelopes. By using the "press-and-seal" envelopes, your QSL Manager will thank you.
* Wax-Paper Nesting. Include a piece of wax paper inside the nested envelope to prevent the envelope from "self-adhering" during transit to the DX station or Manager. Especially helpful when sending to tropical climate areas.
* Return Address on SASE. The QSL Managers address should be placed on the top left corner of the envelope. No one wants a QSL in a "dead-letter" office.
* Pre-stamped SASE. Your card will likely be sent out as soon as it is processed if you pre stamp the envelope, but be sure to affix the proper postage. If you do not pre-stamp, include enough compensation to cover the postal expense.
* Direction of the SASE fold. In many cases you have to fold the SASE to fit within the outgoing envelope. When inserting the folded SASE, do so with the "fold" downwards. if the fold is at the top, the SASE may be sliced in half as it is opened.
* Callsigns on Envelope. Unfortunately in some countries less than honest postal workers have discovered that envelopes labeled "ham radio contest" with call signs are prime targets for green stamps (US currency) within the envelope. If your mail will travel through potential trouble spots, avoid putting your callsign in the return corner. Instead, place your call on the inside, under the flap.
* Avoid registered or certified mail. Either method is inconvient to the QSL Manager, requiring a trip to the post office. This also delays your return wait on the verification. Use of either should be when it is the only way of guaranteeing it is handled properly through a country's postal system.
* Enclosures in the envelope. Shortwave hobbyist and amateur radio operators know the significance of enclosing "goodies" within an envelope. Used postage stamps, souvenir postcards, newspaper clippings of interest, photos, business cards, stickers and decals will likely increase your return rate from the QSL Manager.
