How to Set Up an SMS Drip Campaign

An SMS drip campaign is a series of automated text messages sent to subscribers on a predetermined schedule, triggered by a specific action like signing up, making a purchase, or joining a list. Instead of sending one-off blasts, drip campaigns deliver a sequence of messages over days or weeks, nurturing the relationship and guiding subscribers toward a conversion goal.

How SMS Drip Campaigns Work

A drip campaign starts with a trigger event: a new subscriber opts in, a customer makes a purchase, or a contact is added to a specific list. Once triggered, the campaign sends the first message immediately or after a set delay, then continues sending subsequent messages at intervals you define. Each subscriber moves through the sequence independently based on when they entered.

For example, a welcome drip for new SMS subscribers might look like: Message 1 (immediately after opt-in) sends a welcome and discount code, Message 2 (day 3) highlights your best-selling products, Message 3 (day 7) shares customer testimonials, and Message 4 (day 14) sends a reminder if the discount code has not been used. Each subscriber gets this same sequence starting from their individual opt-in date.

Setting Up a Drip Campaign

Step 1: Define the trigger.
Choose what starts the drip sequence. Common triggers include new subscriber opt-in, first purchase, abandoned cart, appointment booking, or manual addition to a tagged list. The trigger determines which contacts enter the drip and when.

Step 2: Plan your message sequence.
Write each message in the series and decide the timing between messages. Start with 3-5 messages for your first drip campaign. Space messages at least 2-3 days apart to avoid overwhelming subscribers. Each message should build on the previous one and move toward your conversion goal.

Step 3: Set the timing.
Configure the delay between each message. The platform lets you specify delays in hours or days. Also set the sending window so messages only go out during appropriate hours (typically 9 AM to 8 PM in the recipient's time zone). See best times to send SMS for timing guidance.

Step 4: Add exit conditions.
Define when a subscriber should stop receiving drip messages. Common exit conditions include: the subscriber converts (makes a purchase, books an appointment), the subscriber opts out, or the subscriber enters a different drip campaign. Without exit conditions, subscribers might receive irrelevant messages after they have already taken the desired action.

Step 5: Test the full sequence.
Add your own number to the drip campaign and let it run through the complete sequence. Verify that each message arrives at the right time, the content reads well in order, links work, and the exit conditions trigger properly.

Common Drip Campaign Types

Welcome Series

The most important drip campaign for any SMS program. New subscribers are most engaged right after opting in, so a welcome series capitalizes on that attention. A typical welcome series introduces your brand, delivers any promised incentive (discount code, free resource), and sets expectations for future messages.

Post-Purchase Follow-Up

After a customer buys, send a thank-you message, then follow up with usage tips, cross-sell recommendations, or a review request. This drip builds customer loyalty and increases repeat purchase rates without requiring manual effort.

Re-Engagement

When subscribers have not interacted with your messages in 30-60 days, trigger a re-engagement drip. Start with a "We miss you" message, offer an exclusive incentive, and if there is still no response after 2-3 messages, ask if they want to remain subscribed. This cleans your list and recovers some inactive subscribers. See SMS re-engagement strategies for detailed approaches.

Appointment Reminders

For service businesses, an appointment drip sends a confirmation when booked (immediately), a reminder 24 hours before, and a follow-up after the appointment requesting feedback. This reduces no-shows and generates reviews automatically. See SMS appointment reminders for setup details.

Drip Campaign Best Practices

Keep it short. 3-7 messages is the sweet spot for most drip campaigns. Longer sequences see diminishing engagement with each additional message.
Respect frequency. Do not send drip messages on the same day as broadcast campaigns. The platform should coordinate between drips and broadcasts to prevent subscribers from receiving too many messages in one day.
Personalize. Use merge fields to include the subscriber's name and any relevant data (product purchased, appointment time). Personalized drips significantly outperform generic ones.
Measure and adjust. Track which messages in the sequence get the highest engagement and which cause the most opt-outs. Adjust timing, content, or remove underperforming messages based on data.

The platform integrates SMS drip campaigns with the workflow automation system, letting you build complex sequences that branch based on subscriber behavior, combine SMS with email, or trigger actions in other apps.
