LetterStream Promo Codes & Coupons February 2026

LetterStream promo codes are primarily applied during new account creation, not at checkout. This is why entering a code at the final checkout step often triggers an "Invalid promo code" error.

Promo codes are designed to track promotions and add credits (like $10 free for testing) to your account, but they're optional and time-limited, often tied to sales team offers rather than general checkout use.

If your code isn't working, follow these steps:

1. Log out and start a new account at letterstream.com—look for the "promo code" field during signup.
2. Enter the code (e.g., from a blog promotion) and complete registration.
3. Credits will apply to your account balance for mailings like $1.13 First-Class letters.
4. Once credited, proceed to checkout—codes don't apply at payment.

Restrictions: Promo codes are for new accounts only, cannot be applied retroactively, and Customer Support typically won't issue them on demand.

Pro tip: Comment on LetterStream's blog for a chance to get a fresh $10 new-customer code to test mailings risk-free.

No, LetterStream does not support multiple promo codes on any order. Codes are single-entry during account creation only and designed for tracking one promotion per signup.

This limitation stems from their simple pay-as-you-go model—no checkout promo field exists, and attempting to use multiple codes will fail since only one optional code can populate your account balance (e.g., $20 off first order).

No workaround exists for using multiple codes on one account. You could create one account per valid code if needed, but credits don't transfer between accounts.

Restrictions: Codes are for signup-phase only and may expire if not used promptly (e.g., 10-day windows).

Pro tip: Use the highest-value code first (like $10 free credits) on your largest test mailing to maximize savings without splitting orders.

LetterStream promo codes typically apply as account credits usable across all mailing services like First-Class ($1.13/page), Certified ($7.34+), or FedEx 2Day ($13.50), not restricted to specific letter types.

Added credits from codes (e.g., $10 free or $20 off first order) fund any pay-as-you-go mailing, from postcards ($0.78) to variable-page bulk mailings. Enter the code at signup, and credits will automatically deduct from totals at checkout.

Limitations: Credits are typically for new accounts and must cover the full mailing cost (no partial redemptions).

Pro tip: Test code credits on cheaper postcards first to confirm your balance before committing to bulk First-Class runs.

Yes, promo codes add account credits with no explicit bulk mail restrictions, but they're limited to new accounts and must cover the full job cost (e.g., high-volume Certified Mail at $7.34+ each).

Users can apply credits to bulk mailings after signup, but errors may arise if credits expire (e.g., 10-day promo windows) or if using codes on large orders exceeding your balance. LetterStream's model charges per piece (no monthly fees), so bulk works fine if your account is pre-funded.

Steps for using promo codes with bulk mail:

1. Sign up with a code to receive credits.
2. Upload your recipient list and documents; preview costs.
3. Submit—credits auto-apply if sufficient.

Restrictions: Codes are for new users only, cannot be stacked, and are typically sales/team-issued (Customer Support won't provide them on demand).

Pro tip: Request a blog promo code for $10+ credits before bulk uploads to avoid undeliverable address fees on large lists.
