How We Help You

Strengthen Donor Relationships

Save Hours of Work with Our Smart Automations

  • Automate handwritten thank-you notes and campaigns, no more manual mail sorting.
  • Set it up once, and LettrLabs handles the rest, ensuring donors feel appreciated with every mailer sent.

Re-engage Website Visitors Who Didn't Donate

  • Automatically send handwritten mailers to anonymous website visitors who didn’t complete a donation.
  • We uncover their name, address, and even email so you can reach out and encourage them to support your cause.
  • Bring potential donors back with a personal touch that leaves a lasting impression beyond their online visit.

Find More Donors Like Your Best Supporters

  • Build lookalike mailing lists to connect with new potential donors who align with your mission.
  • Target with precision, focusing on individuals who are most likely to engage with your cause.
  • Grow your community by reaching out to those who genuinely care.

Know What’s Working, Down to Each Mailer

  • See who’s interacting with your mail through QR scans and dedicated phone numbers, letting you measure the impact.
  • Track responses down to each individual mailer, gaining insights to refine future campaigns.
  • Keep improving donor engagement by knowing what works, and doing more of it.
