Build a targeted mailing list in seconds.
Stop guessing who your ideal customer is. Use the built-in Lead List Builder to target the exact people most likely to do business with you—including real estate leads like FSBOs, listing drop-offs, and geographic farms—then mail them personalized postcards with printing included.
Geographic Targeting
Build a list from any neighborhood, ZIP code, radius, or city. Focus only on the areas your business actually serves.

Target homeowners, renters, loan-to-value ranges, years in home, and purchase history. Ideal for real estate agents targeting FSBOs, expireds, listing drop-offs, and home services.
Demographic Filters
Narrow your audience by income, age, marital status, education, and more—one smart filter at a time.
Life Events & Milestones
Reach upcoming birthdays, turning-65 lists, new movers, and other key moments that spark buying decisions.

Replace "spray-and-pray" with precision.
Traditional direct mail gets expensive when it's sent to everyone. By targeting only the people who match your ideal customer profile, you reduce waste and turn direct mail into a focused, repeatable channel.

How Mailbox Power Compares to SendOutCards®
See why smart businesses switch to Mailbox Power. While traditional card services charge hefty per-piece fees for additional cards and restrict postcard mailings, Mailbox Power builds unlimited print-on-demand postcards right into your active membership.
| Feature / Plan | SendOutCards® Public Plans | Mailbox Power Membership |
|---|---|---|
| Monthly Fee Options | $27 (Casual) · $47 (Advanced) · $112–$117 (Pro) | $99.99 (Basic) · $199.99 (Professional) |

| Additional Greeting Cards | $3.40 (Casual) · $2.80 (Advanced) · $2.20 (Pro) each | Wholesale Member Overage Rates (Postage + member print) |
| Postcard Mailings | ✖ Billed separately per card (~$1.10 – $1.70 each) | UNLIMITED 5.5×8.5 / 5×7 Postcard Printing Included ($0 Print Fee) |
| 5.5×11 Jumbo Postcard | ✖ Not offered | Available — $0.35 print + postage |
| Dynamic QR Codes | ✖ Static QR generator only — one code per campaign, no per-recipient tracking | Personalized per recipient — unique QR per person with individual scan tracking |

With SendOutCards Pro ($117/mo), you get 50 cards included, but additional cards cost $2.20 each and postcards are charged separately. If you mail 200 greeting cards in a month on SOC Pro, your total cost spikes to ~$447/mo.
With Mailbox Power Professional ($199.99/mo), you get 200 free greeting cards every single month plus unlimited free postcard printing. That gives you 4× the greeting card volume of SOC Pro for less than half the high-volume total cost!
This comparison favors businesses that mail consistently. The savings shown assume regular, ongoing mailings of the kind most businesses send, not occasional one-off cards. If you send only a few cards a month, a lower-volume service may cost less overall, so please weigh your own mailing habits before deciding. SendOutCards® pricing reflects publicly listed rates for Casual, Advanced, and Pro tiers. SendOutCards® is a registered trademark of its respective owner, unaffiliated with Pay Postage Only or Mailbox Power. Rates subject to change.

What could you save
paying postage only?
Pick your membership, choose your postcard format, then dial in how many greeting cards and postcards you'd send in a typical month. Greeting cards are included up to your plan's monthly allotment; postcard printing is included on demand. You pay only the applicable USPS postage — plus the membership fee and any greeting cards beyond your included amount.
4×6 and 5.5×8.5 printing is included ($0) with an active membership. The 5.5×11 jumbo adds a $0.35 print fee per piece.
All 200 within the 200 included each month.
5×7 full-color greeting cards, mailed in a plain white envelope with a blue handwriting-font address and a real first-class postage stamp.
Postcard printing is included on demand — send one or thousands, no minimums.
←→ Tip: click a slider, then use your arrow keys to dial in an exact number.
What another service charges per piece on demand (e.g. SendOutCards Pro at $2.20/card) — printing and postage combined. The per-piece rate shown applies to greeting cards; SendOutCards prices postcards at roughly half that rate (about 50%), so the calculator automatically bills your postcards at the lower rate when a SendOutCards plan is selected. Selecting a SendOutCards plan also folds in that plan's monthly fee for a fair comparison. Drag this to $0 to hide the comparison and just see your Pay Postage Only cost.
Built for businesses that mail consistently. If you send only a few cards a month, a lower-tier plan may cost less, so compare your real monthly volume.
Membership fee amortized across all 700 pieces.
Estimates for illustration only. Postage reflects currently published Mailbox Power rates (65¢ for 4×6, 82¢ for 5.5×8.5 / 5×7 postcards and greeting cards) and is subject to USPS rate changes. The 5.5×11 jumbo carries a $0.35 print fee per piece in addition to postage. Greeting cards are included up to 50/month (Basic) or 200/month (Professional); cards beyond that are billed at member pricing shown for illustration. The membership billing mode adjusts the effective monthly fee: Monthly is the published list price, Annual prepays a year (effectively 2 months free), and Prepaid Promo reflects a limited-time Mailbox Power offer (~$150/mo for Professional) that is not published pricing. The competitor/traditional cost per piece is a blended print-and-mail price (printing + postage) you set for comparison (such as SendOutCards Pro at $2.20/card). SendOutCards publishes that postcards are priced at 50% of the greeting-card rate, so when an SOC preset is selected the full per-piece rate applies to greeting cards and half of it applies to postcards. When a SendOutCards plan preset is selected, that plan's monthly membership fee ($27/$47/$117) is folded in AND its included free cards (5/15/50) are honored — the first free cards are covered by the membership and only the overage is billed at the per-piece rate, so both columns include their membership cost and free-card allotment for a fair head-to-head. Dragging the per-piece slider to a custom value drops the competing membership fee and free cards for a pure per-piece comparison. Membership pricing, postage rates, features, and product inclusions are subject to change. Confirm current details before enrolling. No guaranteed savings or results.
