"The easiest messaging API integration we've done with the most attributable results... Period."

5/5

What do you like best about Sendblue?

We adopted Sendblue across our entire CRM messaging surface from outbound outreach, transactional notifications, two-way customer support, to group campaigns and the impact was visible within the first week. iMessage delivery (blue bubbles) materially lifted reply rates compared to the SMS-only providers we’d used before, and our customers respond faster and more naturally because the conversation looks like every other thread in their inbox.

The API was the easiest integration of any messaging vendor we’ve worked with; we had production traffic flowing in hours instead of the two weeks we’d budgeted. Deliverability has been a standout as well and messages that used to get filtered by carriers on plain SMS routes actually land.

Overall, the net effect is a tighter customer workflow, fewer dropped threads, faster resolution, and a noticeably shorter sales cycle on outbound. For a platform that touches every customer touchpoint we have, it’s been one of the highest-leverage tools we’ve added. Review collected by and hosted on G2.com.

What do you dislike about Sendblue?

Honestly, nothing. We’ve been on the platform for about a month across multiple use cases and haven’t run into any real blockers worth complaining about. The API does what the docs say it does, deliverability holds up, and their team has been responsive whenever we’ve reached out with direct lines of communication via Slack. For now it’s a rare no issues tool in our stack. Review collected by and hosted on G2.com.

What problems is Sendblue solving and how is that benefiting you?

Sendblue consolidated what used to be a fragmented messaging stack for us. Before adopting it, outbound CRM outreach, transactional notifications, two-way customer support, and group campaigns were each fighting their own battle with carrier filtering, deliverability, and an inconsistent customer experience across different SMS providers. With Sendblue, we can handle all four use cases through a single API, which has reduced a lot of integration overhead on our end and gives our customers one consistent thread they can reply to.
