Key Features
Enriched Personalization
Use Apollo's contact data — name, title, company, industry, funding stage — to craft highly personalized iMessages that feel like 1:1 outreach, not mass blasts.
Verified Phone Numbers
Apollo provides verified mobile numbers. Feed them directly into the Sendblue API to reach prospects on their personal devices with blue bubble messages.
REST API Access
Full programmatic control via the Sendblue API. Send single messages or batch outreach, check iMessage availability, and receive delivery webhooks.
Smart Fallback
Sendblue detects iMessage availability automatically. iPhone contacts get blue bubbles; Android contacts receive SMS. No manual segmentation needed.
Webhook Callbacks
Receive real-time delivery and reply notifications. Build automated follow-up workflows that respond to prospect engagement instantly.
Media & vCards
Send images, PDFs, and contact cards alongside your messages. vCards let prospects save your info with one tap — boosting callback rates.
Why Apollo.io + iMessage?
Apollo.io gives you the data. Sendblue gives you the channel. Together, they create a sales outreach workflow that combines the best prospecting intelligence with the highest-response-rate messaging platform available.
The data advantage: Generic outreach gets ignored. When you reference a prospect's company, role, or recent funding round in an iMessage, response rates jump dramatically. Apollo's enrichment data makes every message feel researched and relevant.
Sendblue does not have a native Apollo.io integration — you connect the two via the Sendblue REST API. This actually gives you more flexibility: build custom logic to segment contacts, personalize messages at scale, and route replies to your CRM of choice.
For teams already using a CRM alongside Apollo, Sendblue has native integrations with HubSpot, Salesforce, and Close. You can also connect via Zapier for additional workflow automation.
