What It Is

Delyst is an email marketing and deliverability infrastructure platform registered in Tunisia and labeled “Built in Tunis.” Rather than focusing only on template-based bulk sending, it puts self-hosted KumoMTA, SPF/DKIM/DMARC, BIMI/VMC, bounce classification, Google Postmaster, pre-send checks, and an AI Deliverability Coach at the center of the product. Its goal is to expose delivery details that many other ESPs tend to hide from senders.

Core Capabilities and Channels

Its channel is clearly email; the main content does not mention SMS, voice, or IM capabilities. On the editing side, it offers a drag-and-drop MJML email editor, 30+ templates, double opt-in subscription forms, landing pages, A/B testing, and marketing automation. Deliverability is the stronger focus: 90-day DKIM rotation, DMARC enforcement checks, BIMI/VMC, a three-layer bounce classifier, an 8-point pre-send analyzer, ISP-level throttling reports, bot/proxy open detection, send-time optimization, and more. For APIs, Growth and above include a public API and webhooks, with events covering subscriptions, campaigns, bounces, and complaints; Starter is read-only.

Pricing and Performance

Starter is 19€/month with 15,000 emails/month; Growth is 49€/month with 100,000 emails/month; Pro is 149€/month with 500,000 emails/month and includes a dedicated IP. Annual billing is discounted, and AI credits can be purchased separately. The trial is 14 days of Growth with no credit card required, and new paid subscriptions come with a 7-day refund period. In terms of performance, the site claims 99.9% uptime, API p50 latency below 300ms, and 65+ ISP shaping profiles. That said, the terms also make it clear that no specific delivery rate or inbox placement result is guaranteed, which is a relatively honest stance.

Pros and Cons

The advantages are detailed deliverability visibility, a complete domain authentication chain, exportable data, and relatively transparent cancellation and migration mechanisms. Pro’s dedicated IP and automatic warm-up are well suited to high-volume sending teams. The downsides are that Starter is limited, while BIMI, DKIM rotation, and full API access require higher-tier plans; Starter/Growth also still use shared IP pools by default. The company is based in Tunisia and stores data in the EU, so enterprises with strict local compliance or procurement requirements should review it further.

Best Fit and Access from China

Delyst is suitable for newsletters, SaaS marketing, brand emails, agency multi-client operations, and teams that care about bounce, complaint, and domain reputation analysis. The main content does not provide information on access from mainland China, Chinese-language support, local payment methods, or ICP filing, so china_access can only be considered unknown. If deploying it from within China, first test the console, API, DNS configuration, and Paddle payment flow. Alternatives to evaluate include Mailchimp, Brevo, SendGrid, Postmark, and Mailgun; in China, Tencent Cloud, Alibaba Cloud DirectMail, or SendCloud may be worth considering.
