Nuntly vs Twilio Email API

Nuntly is a developer-focused email platform for sending and receiving transactional email, replying to messages, and tracking activity through one REST API. It supports single or bulk sends, scheduled or immediate delivery, and messages with or without templates. For inbound email, it provides custom inboxes, stored messages, thread grouping, attachment access, webhooks, and a Reply API. The REST API covers domains, API keys, webhooks, analytics, sending, receiving, and team members; documented SDKs include TypeScript and Java. Webhooks expose delivery, open, click, bounce, complaint, and inbound-message activity, with retries, replay, filtering, payload inspection, and signature verification. Logs are retained for up to 30 days. Nuntly says data is encrypted in transit and at rest, and hosted and processed in Europe by default. Its Free plan requires no card and costs nothing; it allows 3,000 emails monthly, 100 daily, one domain, and one inbox. Starter costs €10 a month and allows up to 10,000 emails monthly. Nuntly is headquartered in Châtillon, France.

Twilio Email API lets teams add transactional and marketing email to applications and cross-channel workflows through the Twilio Console. Requests use JSON and can address one or multiple recipients; emails can be scheduled up to seven days ahead. LiquidJS templates can personalize subject, text and HTML fields, while status reporting covers sent, delivered, undelivered, opened and failed messages. Real-time email logs and deliverability tools are included. Requests with attachments have a 10 MB limit and can include no more than 10,000 recipients. The listed pay-as-you-go plan costs nothing, billed per email sent at $0.0013 per email, with no monthly base fee, feature tiers or overage charges. A 30-day free trial offers 100 free emails per day. The API is listed for web and API use, with delivery by API; templates are listed as both and delivery logs are retained for 7 days. Twilio says Email and SendGrid are separate products built on the same email infrastructure, with SendGrid intended for high-volume transactional and marketing email.
