Back to what really matters in customer loyalty. True closeness.

With letter campaigns that fit your customers precisely.

Whether it is a thank you after purchase, reactivating past relationships, or a handwritten note for an anniversary, we build campaigns with you that resonate and stick.

Every campaign is individualized, automated, and tuned in tone and timing to your audience. Personal instead of generic and measurably successful.

Abandoned carts

With our abandoned cart campaign you reach potential customers exactly where digital reminders often get lost: the real mailbox. Instead of another email, your customers receive a tailored letter that feels personal and gently reminds them to complete the purchase.

What goes into these letters?

Typically a strong letter starts with a friendly opener that speaks to the customer directly, for example:

"Hello Ms. Mueller, recently you were interested in our [Product name] - we have reserved it for you again."

This is followed by a short reminder about the cart, possibly combined with tips, benefits, or exclusive offers that motivate the purchase.

Which data do we need?

  • Customer name
  • Address (for shipping)
  • Details about the abandoned cart (product name, variants if applicable)

Optional: time of abandonment, individual discounts or promotions

How the campaign works:

We craft your letters individually so every recipient gets a tailored message.

With Vici-Post you create a tactile experience that captures attention and lifts customer loyalty to a new level.

About the last purchase/visit

Our thank-you letters send a strong signal of appreciation right after a purchase. A handwritten or customized letter stays in memory far longer than a quick email and strengthens the emotional bond with your brand.

What belongs in these letters?

A great thank-you letter begins with a personal greeting, for example:

"Dear Ms. Meier, thank you for your purchase with us. We are happy you chose our [Product name]."

It can express joy about the purchase, include tips for use or care, and preview other highlights or service offers.

Which data do we need?

  • Customer name and address
  • Information about the purchased product (name, variants if applicable)
  • Date of purchase

How the campaign works:

We create personalized letter templates and connect them automatically with your CRM customer data. Shipping happens shortly after the purchase.

With Vici-Post you turn the moment of purchase into a special experience that delights customers and builds long-term loyalty.

It is also possible to include this personal letter directly with the order.

Celebrate a long partnership

With a personal letter campaign that honors long-standing customer relationships, you show real appreciation and strengthen loyalty sustainably. A handwritten or customized anniversary letter conveys closeness and recognition - something digital messages rarely achieve.

What do these letters say?

An anniversary letter usually starts with a warm greeting, for example:

"Dear Ms. Mueller, for [X] years you have been among our valued customers. We sincerely thank you for your trust."

The text can mention shared milestones, hint at future offers, and build anticipation for more years together.

Which data do we need?

  • Customer name and address
  • Start of the relationship or the anniversary date

Optional: information about previous purchases or services

How the campaign works:

We design the letters individually for your customers and connect them with your CRM data. Shipping happens precisely at the right anniversary date.

With Vici-Post you make the anniversary a special moment - for your customers and for your company.

Place a relevant upsell

Use the power of personal outreach to present relevant add-ons or upgrades based on previous purchases. A customized letter grabs attention, feels premium, and makes your offers stand out from digital noise.

What do these letters say?

An upsell letter begins with a personal greeting and a reference to the previous purchase, for example:

"Dear Mr. Mueller, we hope you are enjoying your [Product name]. Did you know we also offer [additional product] that fits perfectly with it?"

The letter highlights the benefits of the upsell product and invites an easy next step - for example a discount code or a personal consultation.

Which data do we need?

  • Customer name and address
  • History of past purchases (product name, purchase date)
  • Information about the upsell products

How the campaign works:

We design the letters individually and connect them seamlessly to your CRM so each customer receives a perfectly matched offer.

With Vici-Post you take your upsell strategy to the next level - personal, appreciative, and with a strong success rate.
