A **Short Code** is one of the most recognizable sending identities in **SMS Marketing**—the 5–6 digit number (for example, 12345) that brands use to send and receive text messages at scale. In **Direct & Retention Marketing**, it plays a practical role: it helps you reach opted-in customers quickly, consistently, and with strong deliverability, especially when timing matters (promotions, alerts, one-time passwords, and service updates).

Shipping is where customer expectations meet operational reality. A **Shipping Update SMS** is a text message sent to a customer to confirm shipping progress—such as “order shipped,” “out for delivery,” “delivered,” or “delayed”—using real tracking or fulfillment events. In **Direct & Retention Marketing**, these messages do more than inform: they reduce anxiety, prevent support tickets, protect trust, and create a dependable post-purchase experience that encourages repeat buying.

Sender Id is the identifier that appears as the “from” field when a text message reaches a subscriber. In **Direct & Retention Marketing**, it’s one of the most overlooked levers for trust, deliverability, brand recognition, and measurable revenue—especially in **SMS Marketing**, where customers decide in seconds whether to read, ignore, or opt out.

In SMS Marketing, message length is not just a creative constraint—it directly affects deliverability, readability, and cost. **Segments Per Message** describes how many billable SMS segments a single text message uses once it’s encoded and sent to a carrier. In **Direct & Retention Marketing**, where teams measure performance down to the cent and the click, understanding Segments Per Message helps you control spend, protect customer experience, and scale campaigns profitably.

Segmented SMS is the practice of dividing your text-message subscribers into meaningful groups and sending each group messages tailored to their needs, behaviors, or context. In **Direct & Retention Marketing**, it’s one of the most reliable ways to turn an inbox-like channel into a performance channel—without relying on broad “send-to-all” blasts that create fatigue and opt-outs.

A **Rich Card** is a card-style message format that combines visual media (like an image), structured text (title and description), and interactive elements (such as buttons) inside a messaging experience. In **Direct & Retention Marketing**, Rich Card experiences are designed to reduce friction—helping subscribers understand an offer quickly and take action without hunting through long text.

Review Request SMS is a customer message sent via text to ask for a rating or written review after a purchase, appointment, delivery, or support interaction. In **Direct & Retention Marketing**, it’s a high-intent touchpoint because it reaches customers quickly, at a moment when their experience is fresh, and it can strengthen trust for future buyers. Within **SMS Marketing**, it’s one of the most common “post-experience” automations—simple in appearance, but highly dependent on timing, targeting, consent, and measurement to be effective.

Replenishment Reminder is a lifecycle message designed to prompt a customer to restock a product before they run out. In **Direct & Retention Marketing**, it’s a high-intent touchpoint because it’s tied to known purchase behavior and expected consumption timing. In **SMS Marketing**, it’s especially effective: text messages are immediate, personal, and well-suited for time-sensitive nudges like “You may be due to reorder.”

RCS Messaging is reshaping how brands communicate with customers in **Direct & Retention Marketing**. Where traditional **SMS Marketing** is limited to plain text and basic links, RCS Messaging supports richer, app-like experiences inside the native messaging inbox—often including verified branding, high-quality media, suggested replies, and interactive buttons.

Quiet-hour Suppression is the practice of preventing outbound messages from being delivered during predefined “quiet hours,” such as late nights or early mornings, when customers are least receptive and most likely to view a message as intrusive. In Direct & Retention Marketing, it’s a customer-experience safeguard that helps brands stay timely, respectful, and compliant while still achieving revenue and engagement goals.

Quiet Hours are defined time windows when a brand intentionally avoids sending promotional (and sometimes non-urgent) messages to customers. In **Direct & Retention Marketing**, Quiet Hours protect the relationship you’re trying to build: they reduce irritation, respect personal time, and support long-term engagement rather than short-term spikes. In **SMS Marketing**, where messages are immediate and highly interruptive, Quiet Hours are especially important because one poorly timed text can trigger opt-outs, complaints, and brand distrust.

Price-drop SMS is a targeted text message sent to a subscriber when a product they care about becomes cheaper—either because the price was reduced, a promotion was applied, or a time-bound deal lowered the effective price. In **Direct & Retention Marketing**, it’s a high-intent moment: the customer has already signaled interest, and the brand uses **SMS Marketing** to turn that intent into a conversion quickly.

Post-purchase SMS is the set of text messages a brand sends after a customer has completed a purchase—typically to confirm the order, provide shipping and delivery updates, offer support, collect feedback, and encourage repeat buying. In Direct & Retention Marketing, it’s one of the highest-leverage moments to communicate because the customer has just demonstrated intent and trust. In SMS Marketing, it’s also one of the most time-sensitive and high-attention message categories, which makes execution and governance especially important.

Popup Capture is the practice of using on-site popups to collect visitor information—most commonly a phone number or email—so you can continue the relationship after the session ends. In **Direct & Retention Marketing**, it’s a core mechanism for turning anonymous traffic into identifiable, reachable subscribers. In **SMS Marketing**, Popup Capture is especially valuable because it creates a permission-based mobile audience you can engage with high open rates and fast response cycles.

Personalized SMS is the practice of tailoring text messages to an individual recipient using known data (such as name, preferences, purchase history, location, or lifecycle stage) and contextual signals (such as recent behavior or timing). In **Direct & Retention Marketing**, it’s a way to deliver timely, relevant communication that feels helpful rather than intrusive—because the message is based on what the customer actually needs right now.

An **Outbound Message** is any brand-initiated communication sent to a customer or prospect to drive action, deliver information, or strengthen the relationship. In **Direct & Retention Marketing**, it’s one of the most controllable levers you have: you decide *who* receives the message, *when* it’s sent, and *what* it says. In **SMS Marketing**, the Outbound Message is especially powerful because it reaches people quickly and typically gets seen fast—making clarity, relevance, and governance non-negotiable.

Opt-out Rate is one of the clearest signals you get from your audience about whether your messaging is welcome, relevant, and appropriately timed. In **Direct & Retention Marketing**, it acts like an early warning system: when Opt-out Rate rises, you’re not just losing a channel—you’re losing permission and future revenue opportunities.

Opt-in Keyword is a simple idea with outsized impact: it’s the word or short phrase a customer texts (or enters into a form) to explicitly subscribe to a brand’s messaging program. In **Direct & Retention Marketing**, that permission moment is everything—because it determines who you’re allowed to message, what you can send them, and how much trust you can earn over time.

MMS Marketing is the practice of sending multimedia messages—such as images, GIFs, short videos, and rich graphics—to customers’ mobile devices as part of permission-based messaging. It sits squarely inside **Direct & Retention Marketing**, where the goal is to drive immediate action (purchase, booking, signup) and build long-term customer value (repeat purchases, loyalty, reduced churn). It also lives alongside **SMS Marketing**, sharing the same mobile-first channel mindset while expanding what a message can communicate.

MMS Creative is the set of multimedia assets and message design choices used in Multimedia Messaging Service (MMS) campaigns—images, animated GIFs, short videos (where supported), copy, layout, and calls-to-action—delivered through mobile messaging. In **Direct & Retention Marketing**, MMS Creative sits at the intersection of immediacy (a message that lands directly in a customer’s inbox) and persuasion (visual storytelling that makes the offer clearer, more desirable, and easier to act on). It’s closely connected to **SMS Marketing** because MMS is typically planned, sent, and measured within the same messaging programs as SMS, even though the creative possibilities are richer.

Message Frequency Disclosure is the practice of clearly telling subscribers how often they should expect to hear from you after they opt in—especially in **SMS Marketing**, where messages are immediate, personal, and tightly regulated. In **Direct & Retention Marketing**, it’s a small line of copy that carries outsized impact: it sets expectations, reduces complaints, and supports long-term list health.

Message Cadence is the planned rhythm of how often, when, and in what sequence you contact customers across direct channels. In Direct & Retention Marketing, it’s the difference between a brand that stays helpful and relevant versus one that becomes background noise—or worse, an annoyance that triggers unsubscribes.

Loyalty SMS is the use of text messages to strengthen customer loyalty through timely, permission-based communication tied to a brand’s loyalty strategy—think points, tiers, rewards, perks, reminders, and recognition. Within **Direct & Retention Marketing**, it’s a high-intent channel for keeping existing customers engaged between purchases and nudging them toward the next valuable action. Within **SMS Marketing**, it’s the retention-focused counterpart to broad promotions: more personalized, more lifecycle-driven, and more closely connected to customer value.

Long Code is a foundational concept in **Direct & Retention Marketing** because it determines how your brand sends and receives text messages at scale. In **SMS Marketing**, a Long Code is typically a standard-length phone number (often a local-looking 10-digit number in some countries) used to exchange messages with customers—especially for conversational, service-driven, or lifecycle communication.

A **Link Shortener** is a system that turns a long, complex destination link into a shorter, cleaner one that’s easier to share, measure, and manage. In **Direct & Retention Marketing**, short links are more than a cosmetic upgrade—they can directly influence deliverability, clicks, attribution quality, and how confidently teams can run fast, measurable campaigns.

Keyword Opt-in is a permission-based method for collecting subscribers—most commonly for SMS Marketing—by asking people to text (or submit) a specific word or phrase (the “keyword”) to join a messaging list. In Direct & Retention Marketing, it’s one of the most reliable ways to turn anonymous interest into a durable, first-party relationship you can nurture over time.

A **Keyword Campaign** is a structured marketing initiative where a specific word or phrase is used as the customer’s “input” to start a trackable action—most commonly by texting that keyword to a phone number or short code. In **Direct & Retention Marketing**, this mechanism is powerful because it turns offline or high-intent moments (a sign, ad, event, packaging, or social post) into measurable, permission-based relationships. In **SMS Marketing**, a Keyword Campaign often acts as the gateway to opt-in, lead capture, customer support flows, and automated promotional sequences.

Inbound Message is one of the most important (and often underestimated) signals in modern **Direct & Retention Marketing**. It’s the moment a customer stops being a passive recipient of campaigns and becomes an active participant—asking a question, confirming an order, requesting support, or replying “YES” to an offer.

In **Direct & Retention Marketing**, small details in the customer journey can determine whether a subscriber stays engaged or opts out. One of the most important—yet often overlooked—details in **SMS Marketing** is the **Help Keyword**: the word (typically “HELP”) that subscribers can text to receive support information or instructions.

Gsm Encoding is one of those technical details in **Direct & Retention Marketing** that quietly determines whether an **SMS Marketing** message is short and cost-efficient or unexpectedly long and expensive. In practical terms, it’s the character encoding used to represent text in an SMS—what characters are supported, how many characters “fit” into a message, and when a single text becomes multiple message segments.
