Envelope stickers add the perfect finishing touch to your personalized stationery. If you’re sending wedding invitations, holiday cards, or handwritten letters, your mailing accessories should match the occasion. Designing custom envelope stickers, also known as sticker seals or envelope seals, allows you to completely personalize your letters. You can even go the extra mile by designing matching envelopes and cards for a cohesive stationery set. Whether you want to make elegant monogram stickers or stylish thank you stickers, GotPrint will add a polished finish to your mail.
Uses for Personalized Envelope Seals
Sending mail doesn’t have to be a thing of the past. Taking the time to send physical letters offers a tangible way to connect with friends or send memorable keepsakes for special events. If you’re the type who loves to send and receive letters, then monogram stickers with your initials add an extra personal touch to your note. Mail is also useful for those who aren’t often writing down their thoughts. Important events like weddings and formal parties will often share physical invites with the guest list. Wedding stationery sets, for example, involve quite a bit of mail—like save the dates, invites, RSVP cards, and thank you cards. Seal all of your wedding envelopes with a custom sticker that seamlessly matches your wedding theme. Other important events can use secure mailed invitations with stickers. Mail invites for galas, charity fundraisers, luxury birthday parties, and other formal gatherings with elegant stickers. Holiday cards can also have themed stickers attached. Send your family Christmas cards alongside a sticker that says, “Happy Holidays,” or share Valentine’s cards with heart stickers.
Envelope Sticker Shape
There are multiple sticker shapes available to customize. Round envelope seals are the classic option. Paired with the sharp lines of an envelope, the circle stickers add eye-catching visual contrast. If you want a quirky sticker, you can print a starburst shaped label, which features sharp points around the circle. Square envelope seals are another popular option, especially if you’re mailing square cards. Other roll label shapes include heart, oval, arched, and rectangle.
Envelope Seal Size
Small roll labels work best for closing envelopes. They should be a feature on an envelope instead of taking up the entire space. For round sticker labels, a 1.5” circle is the traditional size; 1 inch and 2 inch diameters are also popular alternatives. This provides the most space to show off a design without taking up the entire envelope. For square sticker labels, 1” x 1” or 1.5” x 1.5” are the most popular options. Other shapes should also stay under 2”.
Material Options for Envelope Seals
There are several different types of paper you can print your design on. The most durable stickers are printed on White Vinyl Labels. This sticker material is ideal for mailing, as it can withstand indoor and outdoor conditions. If you’re hand-delivering your letters, then you don’t need to worry about how they will hold up against the postal service. White BOPP Labels have a glossy material that adds a sleek shine to your design. The white background will help your colors pop. Clear BOPP Labels share your design with a transparent background, which makes it appear as if it is printed on the envelope. For luxury envelope seals, White Laid Textured Labels have a subtle ridge texture that adds a high-end feel. This option is great for wedding envelope seals or other sophisticated events. All of these options have a permanent adhesive on the back, which will securely attach your sticker to the envelope paper stock.
Envelope Seal Design Tips
With limited design space available, your sticker layout shouldn’t be too complicated. Use a limited color palette and don’t include too many design elements. High-contrast colors help your text or artwork stand out, like using dark text on a light-colored background. Take it one step further by designing envelope stickers that complement the envelope—place a white sticker on a black envelope to catch people’s attention. Since your sticker will likely be placed at the center of the envelope, the design should be centered as well.
