Our Email API combines industry-leading deliverability, intelligent automation, and developer-friendly controls to ensure your emails land in inboxes and your campaigns deliver better engagement and ROI.

Merge customer data dynamically (names, purchase history, account details, behavioral triggers) to craft relevant 1-1 messages at scale. Use conditional content blocks to show different messages based on user’s segments.
Automated Workflows
Trigger email sequences based on user behavior, events, or business logic. From onboarding flows to abandoned cart recovery to re-engagement campaigns, set up sophisticated customer journeys that run on autopilot.
List Management & Segmentation
Manage subscriber lists with advanced segmentation based on demographics, behavior, engagement levels, or custom fields. Automated opt-in/opt-out, preference centers, and suppression lists to maintain compliance and engagement.
Spam Protection
Built-in spam filtering, content analysis, and reputation monitoring catch issues before they hurt your sender score. Our system automatically flags for spam triggers, monitor your sender reputation across major ISPs, and provide alerts to protect your deliverability.

FAQ
Got Questions About our Email API?
Everything you need to know to get started.
How do you ensure high deliverability rates?
We maintain 99%+ inbox delivery through dedicated IP warming, established ISP relationships, authentication protocols (SPF, DKIM, DMARC), continuous reputation monitoring, and feedback loop management.
Can I use my own domain for sending emails?
Yes. Custom sending domains with proper DNS authentication (SPF, DKIM, DMARC) improve deliverability and maintain your brand identity. We provide step-by-step guidance for DNS configuration and verify authentication before you send your first email.
What is IP warming and why is it necessary?
IP warming is the process of gradually increasing email send volume from a new or "cold" IP address to build a positive sender reputation with Internet Service Providers (ISPs) and email providers. Without proper warming, even legitimate emails can land in spam folders or be rejected entirely.
How long does the IP warming process typically take?
A complete IP warming process typically takes 4-6 weeks for most senders, though timing varies based on your sending volume, list quality, and engagement rates. High-volume senders may need 6-8 weeks to reach full capacity, while smaller senders might complete warming in 3-4 weeks.
Do I need a dedicated IP or can I use shared IPs?
You can start with shared IPs, which have established reputation and don't require warm-up. Upgrade to dedicated IPs when you're consistently sending 100K+ emails monthly. Dedicated IPs give you complete reputation control but require a 4-6 week warm-up.
Do you provide email templates?
Yes. We offer a library of responsive, professionally designed email templates. All templates are tested across major email services to ensure consistent rendering.
How does bounce and unsubscribe handling work?
We automatically process hard bounces, soft bounces, complaints, and unsubscribes to maintain a clean sender reputation. Real-time webhooks notify your systems of these events, suppression lists prevent sending messsages to unsubscribed addresses, and detailed bounce categorisation helps you understand deliverability issues.
Can I A/B test my email campaigns?
Yes. Our API supports A/B testing for subject lines, sender names, content variations, and send times. You can define test groups, set sample sizes, choose success metrics (opens, clicks, conversions), and automatically send the winning variation to remaining subscribers.
