Certified mail options for Calendar classic
The new ONESOURCE Calendar doesn't support direct printing of certified mail forms. You can keep your current vendor or switch to a different one.
You have several options for printing the needed forms when you move from classic:
- Add your current addresses to your certified mail provider's site. When you need to print certified mail forms, select the addresses and print.
- Add the address information for each classic Event into the new ONESOURCE Calender custom fields. When you're ready to print the certified mailers:
- Export a file with the addresses and then import it directly into the vendor's website to print.
- Use APIs to pull data from Calendar and trigger your vendor's APIs to print the forms.

Many options are available to obtain certified mail services. Each vendor may differ in their requirements. For example, some vendors require you to buy forms while others let you print directly. Some vendors require address imports in CSV format while others use Excel. Some vendors offer APIs to automate the process. Most websites also provide a PDF of the confirmation, which you can now add directly to the new Calendar as an attachment.
