  "account": "Before sending your first transactional email from a new domain, there are five crucial steps to ensure a smooth launch. First, choose a subdomain for your emails, such as mail.example.com or news.example.com, rather than using the root domain directly. This precaution protects your primary domain from any reputation issues that might arise with the subdomain. Second, prioritize the implementation of DKIM, followed by SPF, then DMARC. This sequence ensures that the email's authenticity is verified, and it prevents the breakdown of SPF when messages are forwarded. Implementing a strict DMARC policy after establishing DKIM helps maintain a good sender reputation.\n\nNext, begin with a simple and reputable email, such as a password reset sent to your own address, to ensure that all email components are functioning correctly. Check the raw email headers to confirm that the DKIM signature is valid, the return path matches the sending domain, and any bulk emails include a List-Unsubscribe header. Gmail's \"Show Original\" button can be used as a quick testing tool for this purpose.\n\nFourth, log the unique provider-assigned message ID, not just your internal message identifiers. This step is crucial when customers report that an email did not arrive, as it allows you to reference the exact message identifier assigned by the recipient's server. Keeping this information alongside your delivery logs will streamline any deliverability investigations. Lastly, ensure that your email sending process is designed to be idempotent. This means that if the system retries sending an email due to a timeout, the system should not produce duplicate emails. This is achieved by including an idempotency key in the send request, which helps prevent duplicate receipts of the same email. Volanea provides a streamlined solution for managing DNS settings per sending domain and offers a delivery log dashboard, simplifying steps 2 and 4 instead of requiring manual shell commands.",
  "summary": "Sending your first transactional email from a new domain is where most launches quietly lose their first hundred signups. Not because the code is wrong, but because the domain has no reputation and the DNS records are half done. 1. Pick a subdomain, not the root Send from mail.example.com or news.example.com, never from example.com itself. If the sending subdomain gets a bad reputation, your…",
