Every October 7, the propane industry pauses to celebrate National Propane Day, and it’s the perfect moment to think about how we’re keeping our customers safe. For propane providers, that means sending out their annual safety mailings. It’s one of the simplest ways to build trust with customers. A well-timed, well-designed safety mailing can be the difference between a customer who understands the warning signs of a leak and one who skims past an envelope they mistake for junk mail.
Here’s how propane providers can help ensure their Duty to Warn mailings are actually read.
Send Letters Individually
Bundling safety information with a monthly statement or invoice makes it easy to miss. A standalone letter, in its own envelope, tells customers this piece of mail matters.

Mail Before the Holiday Rush
Once the holidays hit, mailboxes fill up fast. Getting the Duty to Warn mailing out before the season ramps up gives customers a better shot at opening and reading it.
Reinforce Safety Year-Round
One mailing a year is a good start, but safety messaging works best when it shows up more than once. Sharing tips through email, social media, or bill inserts throughout the year keeps propane safety top of mind for customers, not just something they see once and forget.
