Attentive: AI‑led Email &SMS

We migrated from Klaviyo for our emails in Aug 25 (been sending SMS since start of 2025) and we find the platform to be super intuitive and easy to use. Great to have both sms and email in the same place. We've had a couple of small issues in the past which were resolved by the attentive team with relative speed. It's great to have a managed service to provide recommendations on both campaign and journey strategies. Overall happy with the move.

We migrated from Klaviyo to Attentive at the back end of 2025. The process has been seamless. Performance has increased massively using the full suite of Attentive SMS and email software.

We're really happy with our account management, Sam actively optimises accounts and suggests improvements, even when we're too snowed under to give the channel the attention it deserves.

Can't recommend Attentive enough.

Nearly 6 months into using Attentive and really happy with the service so far, it's not been without a few hiccups, but the team have been incredibly helpful and quick to rectify! Already seeing a huge improvement from our previous SMS provider, so very excited to see how we grow with them.

We switched to Attentive in October last year and have really been enjoying the platform ever since. The team has been incredibly helpful in supporting us as we optimise our SMS programme and the analytics/ reporting tools are both excellent and very easy to use. The support from the White Glove team has been fantastic, especially through the live chat feature whenever we’ve needed assistance. Overall, it’s been a great experience so far.

The team has been great to work with. I’ve been with them for years, and they’ve been consistently responsive. Luke has taken good care of us

Great platform for growing SMS revenue through campaigns and flow. Team is very supportive for any issues and helps plan out future campaigns. Easy to use and make changes quickly

Top tier platform. Top Tier team. Nothing but flawless execution in helping get anything set up & moving. Shoutout Maya & Dom

Attentive’s platform itself is fine, but the contract structure and enforcement approach are extremely restrictive and disappointing.

The agreement includes strict SMS exclusivity with long-term lock-in, limited flexibility, and significant financial penalties (more than reasonable costs) if you need to adapt your tech stack. Even more frustrating, the Attentive team has taken an overly aggressive interpretation of the contract—suggesting that even discussing or planning with other providers would be a breach, despite that not being clearly supported by the language.

For a fast-growing e-commerce business, this makes it very difficult to evolve, evaluate alternatives, or integrate with tools Attentive doesn’t support. When integration gaps arise, the exclusivity still applies, leaving you stuck paying for services that no longer meet your needs.

If you value flexibility, vendor interoperability, or the ability to plan ahead without pressure tactics, read the contract very carefully before signing.

We made the move to Attentive expecting an initial guided walkthrough and hands on support, but that hasn’t been my experience so far.

I was billed for 21,000 messages that I did not send, and despite reaching out multiple times, I haven’t been given a clear explanation of where those messages came from. I keep getting transferred between teams and sent help articles that don’t actually answer my questions. I’m simply looking for clarity and direction.

What was promised for billing has not aligned with what I’m seeing.

I understand transitions can be confusing, but this has been more difficult than expected.

Much of what I thought would be supported, including setting up flows and getting email and SMS working properly, has ended up being something I’ve had to figure out on my own. I’m still confused.

If you have the time to research, troubleshoot, and figure things out independently, this may be a great app for you. However, if you’re like me and made the move based on the promise of hands on support, I would approach with caution.

Attentive has been a great addition to our marketing toolkit. The platform is intuitive, and provides clear insights that help us optimize our campaigns. Their customer support team is also super responsive and helpful.

However, one downside is that we don’t have a dedicated account manager, which sometimes makes it harder to move fast or make adjustments. There are certain features or changes that can only be made through their team, which adds some extra steps and limits flexibility.

Overall, Attentive is still a powerful tool that’s helped us improve engagement and conversions, but having more autonomy inside the platform would make it even better.
