Klaviyo and Attentive.

Attentive is an SMS marketing platform, and many stores run it alongside Klaviyo email. Whether and how the two share data depends on your setup, so check the current documentation for both before you rely on a sync. The key work is coordinating consent and timing so a customer is not messaged by both channels about the same thing.

What Attentive sends to Klaviyo.

• SMS consent. Where shared, whether a person has agreed to text messages, which must be treated as separate from email consent.
• SMS sign up source. Where a person joined, such as a pop up or checkout, useful for reporting and welcome messages.
• Message activity. Sends, clicks or replies, where the connection reports them, which varies by setup.
• Phone number data. The number tied to a profile, which needs correct formatting and permission to use.
• Purchase and cart activity. Commerce signals that either tool may use for triggers, so decide which channel owns each trigger.

Flows it enables.

• Welcome across channels

  Greets a new subscriber by email and, if they agreed, by text, without repeating the same offer.

• Abandoned cart coordination

  Decides which channel goes first and holds the second back, so a shopper gets one reminder not two.

• Post purchase

  Email carries the detail while text, if used, stays brief and useful, such as delivery updates.

• Channel preference campaigns

  Segments people by the channels they agreed to and sends each the right message.

Setup order.

1. 1. Check the supported connection

   Read the current Attentive and Klaviyo documentation to see what can be shared.

2. 2. Map consent separately

   Keep email and SMS consent distinct, and record the source and wording of each.

3. 3. Decide trigger ownership

   For each trigger such as cart or welcome, name the channel that leads.

4. 4. Test the data

   Sign up with a test number and email and confirm what each platform shows.

5. 5. Build the cross channel logic

   Use delays and conditions so the second channel does not fire straight after the first.

6. 6. Review quiet hours and frequency

   Set sensible send windows for text, which is more intrusive than email.

Common pitfalls.

• Treating email consent as permission to send texts.
• Both tools firing a cart reminder at once.
• Sending text outside sensible hours.
• Poorly formatted phone numbers causing failed sends.
• Not recording when and how consent was given.

Apps and Klaviyo both change their screens and options over time, so confirm names against what you see and check each app's own documentation for current details.
