Pro-life organizations usually have many simple yet time-consuming tasks their staff could use help with. Sending thank you notes is a great example–this job is an important part of donor stewardship, which is an important part of the financial health of the organization. Larger orgs will likely have automated this process (although it can’t hurt to contact them and make sure), but smaller groups may still be sending handwritten notes. The same may apply for holiday cards or event invitations. Contact your preferred organization(s) and see if they need the help.
