Benefits of printing and mailing letters to your customers


Easily customize each letter for your target audience, and print and mail letters online using our letter API. Direct mail is the best way to ensure your customer receives your message and you have access to them directly unlike its digital counterpart where messages can be lost in spam or junk folders.

Personalization instills a sense of value in its readers and gets their attention ensuring a higher response and engagement rate.


The letters sent through direct mail can be targeted just like an email marketing campaign if you choose to do it through an automation tool like PostGrid. Reach the right people with the relevant offers, and eventually increase your client base and returns using our letter mailing service.


While email fills the inboxes at supersonic speed and feels like sent from a machine, the tangible and personalized letters make your potential customers feel more valued. Hence, they’re a great way to convey your message and improve your brand awareness.

High Reach

Compared to only 34% of people with internet access, approximately 95% of the world’s population has access to postal services. With this stat in mind, it’s a no-brainer that you should go for direct mail marketing than opting for digital marketing alone if you want to reach a wider audience.


Whether you want to send one letter or one thousand, with the help of letter printing and mailing services like PostGrid, you can customize all of your letters before sending them. You can get your customers’ first names, your company’s logo, website, or a personal message printed on the letters hassle-free. Since the open rate of direct mail is way better than email, you can take advantage of this with personalization and improve your customers’ engagement.

Provide Value

More than often, businesses reach out to their audience through email, if you’d send personalized letters, they may get a better response rate as your prospects would feel valued. This method conveys a message that you took an extra step to communicate with your customers and, in return, it would strengthen the relationships with your customers and prospects and increase sales.

Type of Letters That You Can Send

Welcome or Thank You Letter

Without a doubt, the welcome message has the highest open rate. Yet, half of the businesses take it for granted. They send welcome or thank you message to their new customers in the form of direct mail letters, and use this opportunity to grab as much more information about them as they can. So, they can deepen their relationships with them. If you need to upsell, stop missing out on such great opportunities, which lie in front of you just like that. And start sending thank you and welcome letters to your customers for better engagement and excellent results.

Products or Events Promotion

“This letter is worth $1,500 to you when you buy or lease a brand new Lincoln,” It was the headline of one of the promotional letters that Ford Canada sent. And this one letter helped the company get half of their sales for six months straight. So, if you choose a tangible form of letters to promote your products and events – with valuable and direct content – you can increase your sales tremendously. In addition, they have an excellent open rate, so if your content is good, no one can stop you.

Follow-up Letters

Follow-up emails are a part of almost every business, but if you send your prospect, or perhaps your customers, a letter informing them about what’s more or what they’re missing out on, you can expect great engagement and more repeat businesses. With better returns, you can also recoup the cost of your tangible letters.

Query Letters

Send your prospects query forms with the letters they can fill out and send back to you. It’ll help you know how many people are interested in doing business with you. Later on, you can follow up that particular set of audiences with relevant offers.
