What is SMTP Senpai?

MailSenpai's SMTP Senpai acts as a reliable SMTP relay for all your email needs, including sign-ups, password resets, order confirmations, notifications, and contact forms generated by your applications, websites, and tools. You can easily connect using standard SMTP on port 2525 or 587 with STARTTLS, a REST API that delivers JSON responses, or a specialized form endpoint that works seamlessly with web forms, even on static websites. All outgoing emails are authenticated with DKIM using your domain, and we provide the necessary DNS records while verifying them for you. We automatically manage bounced addresses, keep a comprehensive 90-day log of all sent emails, and deliver an in-depth weekly report for your records. Instead of suspending your account when you exceed a specific limit, we offer warnings and guidance on how to address any issues that arise. Our operations and servers are located in the EU, and we provide customer support in both Italian and English through ticketing and email systems. You can explore our offerings with a 14-day free trial that requires a credit card for registration (cancellation is available at any time), and after the trial, you can choose a subscription plan starting at €12.90 per month for up to 10,000 emails annually. With this service, you can enjoy dependable email delivery while benefiting from the flexibility and support tailored to enhance your communication requirements. Additionally, our commitment to data security and compliance further strengthens our service's reliability.

What is Prime Dev Force Security?

Prime Dev Force Security conducts an external evaluation of a website's security setup, offering insights on the most critical issues that need immediate attention. By simply entering a domain you manage, results can be obtained in about 3 to 15 seconds, which include assessments of HTTPS configurations, redirects, TLS certificates, security headers, DNS settings, and email authentication methods such as SPF, DKIM, and DMARC. Each detected problem comes with supporting evidence, along with severity and confidence ratings, and is complemented by comprehensive remediation instructions organized into a prioritized task list for your ease of use. This free service does not necessitate any account registration. For a monthly fee of $12, the Pro version enhances the service with daily monitoring, notifications, and a server agent for your owned sites, while the Agency plan, available at $49 per month, supports up to 30 client domains and offers branded reports tailored for clients. It’s crucial to understand that this service performs an outside-in configuration check, which distinguishes it from a penetration test, as it does not examine pages requiring login credentials. Overall, utilizing this tool is vital for maintaining the security and compliance of your website with industry best practices, ensuring peace of mind for website owners. Additionally, the user-friendly design of the service makes it accessible for individuals and businesses alike to bolster their online security effectively.
