Netcore Email API vs SparkPost Comparison: Everything You Need to Know Before Choosing

Netcore Email API, formerly known as Pepipost, is a cloud-based transactional and bulk email delivery service from Netcore Cloud, the Indian customer engagement technology company. It is designed for developers and product teams who need to send application-generated emails, such as account alerts, invoices, one-time passwords and notifications, at scale and with high inbox placement. Pepipost originally differentiated itself with a pricing model that did not charge for emails that were opened, and the service continues to focus on cost-effective, high-volume delivery. Its core approach combines an API-first sending architecture with deliverability expertise and analytics, so that businesses can integrate email quickly and rely on the provider to manage infrastructure, reputation and compliance with mailbox provider requirements. Pricing and plans are structured around email volume, and the platform has been adopted by businesses sending anything from a few thousand to many millions of messages each month, making it a flexible option as sending needs change and grow over time. Key features include RESTful APIs and SMTP relay, client libraries for common languages, dynamic templates with personalisation, webhooks for real-time event data, and detailed logs covering delivery, opens, clicks, bounces and spam complaints. Deliverability tooling includes domain authentication guidance, dedicated IP options, suppression list management and AI-driven insights that help identify issues affecting inbox placement. Integrations with platforms such as WordPress, Magento and Zapier broaden its reach beyond custom applications, and the service forms part of Netcore's wider suite covering marketing automation, personalisation and multichannel engagement. It is fully hosted and scales to very large volumes, which suits fintech companies, e-commerce businesses, online marketplaces, media publishers and SaaS providers, particularly in India and other Asian markets, as well as global senders. A free version with a limited sending allowance is available, alongside a free trial, and paid plans start from around USD 25.
