BLACKLINE Support

Tell us what happened, which device you used and whether the issue concerns a stencil, membership, payment or saved project.Last updated 23 August 2026

Contact

Email blacklinestencil@gmail.com. Include the email attached to your BLACKLINE sign-in, but never send a password, card number, Stripe secret key or other financial credentials.

For a stencil problem

Keep the original and stencil, describe the area that does not register, and include a side-by-side screenshot if it is safe and you have permission to share it. BLACKLINE creates AI interpretations rather than exact copies, but a clear report helps distinguish an expected artistic simplification from an alignment or generation fault. Do not email confidential client photography unnecessarily.

Quick checks

  • For a free stencil, Artist or Pro, request a fresh BLACKLINE sign-in code using the same verified email attached to the account.
  • Your free stencil is available once per verified email account per UTC calendar month and can be downloaded without a watermark or payment card.
  • Pro adds 50 stencils each calendar month and rolls unused Pro stencils up to 100 while active. Purchased packs remain separate.
  • For a one-off pack, sign in with the same verified email used at checkout. The unused balance follows that account across supported devices.
  • Use a JPG, PNG or WebP under 20 MB and keep the browser open while generation finishes.
  • If a failed job still appears counted, refresh the account once before contacting support.
  • For lettering, anatomy or orientation, compare the full output with the source before transfer.
  • Pro printing opens an A4 PDF. On iPhone or iPad, tap Share, then Print in the PDF. Choose A4 and single-sided printing. If Scale is available, choose 100% or Actual size and turn Fit to page off. Measure the 5 cm test line.
