How to Combine Email and SMS in One Drip Sequence

The most effective drip campaigns use both email and SMS together. Email delivers detailed content, images, and links, while SMS gets immediate attention with short, time-sensitive messages. Combining them in one coordinated sequence gives you the reach of email and the urgency of text messaging, producing higher engagement and conversion rates than either channel alone.

Why Cross-Channel Drips Outperform Single-Channel

Email open rates typically range from 15-25% for marketing messages. SMS open rates consistently exceed 90%. But SMS has a character limit and higher per-message cost, making it impractical for detailed content. By using both channels strategically, you reach contacts through whichever medium they engage with most while keeping costs manageable.

A cross-channel approach also provides natural redundancy. If a contact misses your email (it lands in the Promotions tab or they just do not check), the SMS follow-up still gets through. And if they read the email but do not act, a well-timed text can nudge them to take the next step.

How to Structure a Combined Sequence

Step 1: Plan the full sequence on paper first.
Before building anything, map out every touchpoint across both channels. Write down each message, its channel (email or SMS), its timing, and its purpose. For example: Day 0 Email (welcome), Day 1 SMS (quick check-in), Day 3 Email (educational content), Day 5 SMS (reminder about offer), Day 7 Email (case study), Day 9 SMS (last chance). Planning on paper prevents channel conflicts and ensures the timing feels natural. See How to Plan Your First Drip Sequence.
Step 2: Set up the email drip sequence.
Create the email portion of your drip in the Email Broadcast app. Build a contact list, write the email messages, and configure the email schedule with the days and times you planned. Follow the steps in How to Set Up an Email Drip Campaign. Make sure the email schedule only covers the days when email messages should send.
Step 3: Set up the SMS drip sequence.
Create the SMS portion in the SMS Broadcast app. Build a separate contact list for SMS, write the text messages, and configure the SMS schedule. Follow the steps in How to Set Up an SMS Drip Campaign. Coordinate the SMS schedule days so they interleave with your email days rather than overlapping.
Step 4: Synchronize contact entry across both lists.
When a new contact enters your funnel, they need to be added to both the email list and the SMS list at the same time so both sequences start together. The easiest way is to use a workflow automation that triggers on the initial action (form submission, chatbot capture, purchase) and adds the contact to both lists in one step. This keeps the two drip timelines aligned.
Step 5: Coordinate timing to avoid overlap.
Do not send an email and an SMS on the same day unless one is a deliberate follow-up to the other (for example, an email with details in the morning and an SMS reminder to open it in the afternoon). As a rule, alternate channels across days. If you send an email on Monday, send the SMS on Wednesday, then the next email on Friday. This spacing prevents contacts from feeling bombarded while keeping your brand in front of them.
Step 6: Test the full cross-channel experience.
Add yourself as a test contact to both lists simultaneously. Over the next week or two, receive every message on both channels. Check that the timing makes sense, the messaging is consistent (not contradictory), and the calls to action build on each other. Verify that unsubscribing from SMS does not affect the email drip and vice versa, since contacts may want to stay on one channel but not the other.

Best Practices for Cross-Channel Drips

Use Each Channel for What It Does Best

Keep Messaging Consistent but Not Repetitive

Both channels should feel like they come from the same brand with the same voice, but do not send the identical message on both channels. If your email offers a 15% discount, your SMS can remind them about it ("Your 15% code expires tomorrow!") without repeating all the details. Each message should add value rather than duplicate.

Respect Channel-Specific Preferences

Some contacts will engage heavily with email but ignore texts. Others will read every SMS but rarely open emails. Track engagement on both channels and consider adjusting. If a contact has not opened your last three emails but reads every SMS, lean into the SMS channel for critical messages.

Consent note: Email and SMS require separate consent. A contact signing up for your email list does not automatically give you permission to text them. Make sure your opt-in forms clearly state both channels if you plan to use both, and give contacts the option to choose one or both. See SMS Opt-In and Opt-Out and Dual SMS and Email Opt-In.
