Have you ever wondered how many customers have messaged your Fanpage to ask about prices or product consultations but then went silent? For shops that have been operating for 1 to 2 years, this number typically ranges from several thousand to tens of thousands of people. While the cost of acquiring new customers (CAC) through Facebook advertising continues to rise, the database of former customers sitting in your inbox is being neglected like an untapped gold mine. The service Facebook Fanpage Old Customer Reinbox by DPS.MEDIA is a natural remarketing solution that helps you reconnect with this entire customer database at a cost of over 80% less than conventional advertising.

Instead of continuing to burn money on new message ads with increasingly expensive bids, discover how to reactivate this pool of potential customers safely, intelligently, and sustainably.

What Is Fanpage Reinbox? Why Is It a Wasted Gold Mine?

Simply put, Reinbox is the process of sending customer care messages, discount codes, or promotional announcements directly to the Messenger inboxes of people who previously initiated conversations with your Fanpage. This is a form of one-to-one engagement with an actual message open rate of over 85% – significantly outperforming email marketing and regular feed posts.

Existing Customers: The Customer Segment with the Highest Conversion Rate

A customer who has previously messaged your Fanpage already knows your brand, is interested in your products, and has genuine purchasing needs. Unlike cold audiences who must go through multiple brand awareness stages, existing customers may only need a timely incentive (a 15% discount voucher, a notification about newly arrived products, or a birthday appreciation promotion) to be ready to return and place an order. At Mia Shop Fashion, for example, just 3 days after launching a remarketing message campaign targeting 4,200 existing customers, the shop generated 142 orders with revenue exceeding VND 58,000,000 without spending a single additional đồng on new advertising.

Comparing Natural Reinbox with Sponsored Messages Advertising

Previously, the only way to send messages to existing customers again was to purchase Sponsored Messages through Meta Ads Manager. However, this approach has three major drawbacks: extremely high CPM costs (ranging from VND 150,000 to VND 350,000 per 1,000 message impressions), a strict advertising approval process that can easily result in rejection, and messages displaying a “Sponsored” label that may make recipients wary. Reinbox technology simulates natural user behavior, allowing you to send messages directly from your Page inbox. They appear like ordinary customer care conversations, with an all-inclusive cost of just one-fifth of the price.

2 Flexible Implementation Options at DPS.MEDIA

Depending on your business size, staffing resources, and budget, DPS.MEDIA offers two clearly defined implementation options for customers to choose from:

1. Reinbox Managed Package: Fully Managed A-to-Z Service by DPS Specialists

This is the ideal solution for business owners, retail chains, and busy shop owners who do not have time to operate a computer. You simply provide your promotional idea or the campaign you want to launch, and the DPS.MEDIA team will handle all the remaining steps:

• Sales Message Copywriting: DPS's professional copywriting team creates concise, highly persuasive messages that focus directly on customer benefits and encourage action.
• Multi-Layer Spin Content Setup: Combine dozens of sentence structures and synonyms so that every outgoing message is unique and does not contain duplicated text.
• Promotional Banner Design: Professionally designed graphics are attached to messages to increase credibility and visual appeal.
• Audience Extraction and Data Filtering: Extract the entire Page inbox history while excluding failed conversations and invalid contacts.
• Safe Message Delivery Management: Configure randomized time intervals and simulate real human actions in the browser.
• Completion Report: Provide a report detailing the number of successfully delivered messages after the campaign ends.

2. Reinbox Eco Package: Extension Provided for Self-Managed Operations

If you are an individual business owner or a small shop looking to minimize costs and maintain full control over your schedule, the Reinbox Eco package is an extremely cost-effective solution, priced at just VND 100,000 / month. Customers receive a license for a dedicated browser extension (Chrome Extension), along with installation guidance from a technician. Afterward, you can prepare your own content and send messages whenever you want.

Fanpage Safety Protection Technology: No Unrealistic Guarantees

One of the biggest concerns shop owners have when considering bulk messaging is the fear of their Fanpage losing messaging functionality or having its inbox access restricted. At DPS.MEDIA, we operate based on technical transparency and integrity, and never make empty promises such as “100% guaranteed safety”.

Meta Platform Policies and the Technical Reality

Meta's (Facebook's) algorithms continuously scan activity and can change at any time without prior notice. Any service provider promising “100% absolute safety” is making misleading advertising claims. However, risks can be minimized if you understand how spam filters work.

Multi-Layer Spin Content Mechanism: Preventing Spam Detection

Facebook's filters detect spam when they identify an account sending hundreds of identical messages within a short period. To prevent this, DPS.MEDIA applies advanced text-spinning syntax:

{Hi there|Hello|Hi|Good day} {there|!|}! {Our shop|We|DPS} would like to offer you {a 20% discount code|a 50k voucher|a special offer} for {the weekend|our shop's birthday|customer appreciation}…

With this formula, each customer receives a message with a completely different opening, form of address, and sentence order. Facebook's machine-learning system may recognize these as separate, natural conversations.

Simulating Real Human Behavior in the Browser

Instead of sending messages simultaneously through APIs and potentially causing connection congestion, DPS technology introduces randomized pauses of 15 to 45 seconds between messages. Scrolling through pages, opening chat windows, typing individual characters, and attaching images are all performed sequentially, just like a dedicated employee working at a Page inbox. This helps maintain the Fanpage's trustworthiness with Meta.
