Order Creation Email API

The core difference lies in Amazon SES's capability to handle both transactional and marketing emails, which makes it powerful but also susceptible to issues with spam control. This often results in a significant number of IPs being blacklisted by ISPs, leading to occasional delivery failures. In contrast, AotSend's email API product was designed exclusively for transactional and trigger-based emails such as reminder email, authentication email, confirmation email, notification email, verification code email, info email, triggered email, OTP emails, 2FA emails, billing emails, etc. AotSend strictly prohibits the use of SMTP and only allows API-based sending of pre-approved templates. The strict limitations on SMTP technology and predefined email content provide direct advantages, including a delivery rate exceeding 99% and an inbox rate exceeding 96%. This significantly reduces the risk of losing customers due to occasional undelivered emails caused by IP blacklisting. Additionally, Amazon SES offers relatively basic data analytics compared to AotSend, lacks global intelligent acceleration, and does not support automatic variables. AotSend excels in these areas, providing more robust features and capabilities.

Based on the premise of sending transactional emails, if your domain is an old domain with a history of consistent email sending, trigger-based emails sent from this domain typically go directly to the inbox after domain DNS configuration. In rare cases, some old domains may require a 1-5 day warm-up period before achieving inbox delivery. For new domains, after initiating email sending, the inbox rate generally increases gradually over a domain warm-up period of 3-15 days, progressing from 20%, 40%, 60%, to 80%, and eventually exceeding 90%. As you continue to send emails over time and accumulate sending volume, the domain's reputation will increase, leading to a delivery rate that gradually exceeds 99%. The exact timeline depends on your average daily email volume and the email content. It's important to note that new domains typically lack reputation and a sending history, which may result in emails being delivered into spam folders initially due to not being whitelisted by mail servers. This is a normal and temporary occurrence. As long as you consistently send legitimate trigger-based emails and avoid significant spam reports, your emails will gradually be recognized as legitimate and increasingly delivered to recipients' inboxes. With continued stable email sending practices, both delivery and inbox rates will improve. Customers should not be concerned about this process.

For the AotSend email API interface, improving delivery and inbox placement rates involves several key strategies. First, it's crucial to rigorously maintain a legitimate customer base and minimize potential risks. Second, increasing the reputation of email IPs by maximizing valid sends and reducing invalid ones is essential. Lastly, optimizing email template content and incorporating advanced predefined variables can significantly enhance email delivery and inbox placement rates. From the customer's perspective, adhering strictly to AotSend's email categorization and template guidelines when calling the API and sending emails is paramount. Secondly, verifying email authenticity before triggering email sends—ensuring the email addresses are valid—increases the effectiveness of email sends. Finally, using advanced variables in the email API judiciously and appropriately to diversify email template content helps boost inbox placement rates effectively.
