Description
Postmastery delivers a comprehensive platform for professional email monitoring that extends well beyond mere ‘click & open’ metrics. Its Delivery Analytics system analyzes SMTP delivery information from both local mail servers and SMTP service providers, incorporating data from Microsoft SNDS, Return Path Sender Score, along with various blacklists. Users are equipped with real-time dashboards and benefit from automatic notifications. Issues like high bounce rates, prolonged delivery times, landing in junk folders, or being blacklisted can severely hinder email marketing efforts and adversely affect your company's reputation. To proactively manage these challenges, Postmastery establishes a benchmark for improvement and conducts thorough email delivery evaluations. Additionally, should the situation require it, our team offers direct support at the infrastructure level. By turning to Postmastery for your delivery monitoring needs, you can concentrate on your primary business operations while leveraging our extensive email delivery expertise, tools, and resources available through our 'email delivery control centre.' This partnership ensures that your email campaigns are not just effective but also aligned with best practices in the industry.
Description
SMTP Senpai, offered by MailSenpai, serves as the SMTP relay for emails generated by your applications, websites, and tools, handling everything from sign-ups and password resets to order confirmations, notifications, and contact forms.
You can connect using standard SMTP (port 2525 or 587 with STARTTLS), a REST API that provides JSON responses, or a dedicated form endpoint suitable for web forms, even on static sites.
All outgoing emails are DKIM-signed using your own domain, for which we supply the necessary DNS records and verify them on your behalf.
Automatically, we suppress bounced addresses, maintain a 90-day log of all sent emails, and provide you with a comprehensive weekly report.
Rather than suspending your account upon exceeding a certain threshold, we issue a warning and guide you on what needs to be addressed.
Our servers and data operations are based in the EU, and we offer support in both Italian and English through tickets and email.
Try us out with a 14-day free trial that requires a card for registration (you can cancel anytime), and then continue with plans starting at €12.90 per month for up to 10,000 emails on an annual subscription.
This service ensures reliable email delivery while offering flexibility and support for your communication needs.
