Common Questions About Choosing AotSend Email API

Why Choose AotSend Email Delivery API? What are our key features? How do we differ from and excel over similar triggered email API products?

2 Q&A

AotSend email API service philosophy revolves around: niche segmentation, simplicity with robustness, and dedicated stability. This means developing vertical email products tailored to specific industries, ensuring user-friendly yet powerful functionalities, and focusing on stable email delivery through dedicated IP pools for triggered emails. Key reasons to choose AotSend Transactional Email API provider include: competitive pricing at 0.28USD per 1000 emails, dedicated IP pools, IP rotation, Accurate data analytics, global sending acceleration, intelligent global acceleration, automatic record deletion after 7 days, dynamic variables, pre-set email templates, and comprehensive email data tracking capabilities.

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 email delivery failures. In contrast, AotSend Transactional Email Platform product was designed exclusively for transactional and triggered 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 Transactional email api strictly prohibits the use of Email SMTP API and only allows API-based sending of pre-approved templates. The strict limitations on Email SMTP API technology and predefined email content provide direct advantages, including a email delivery rate exceeding 99% and an inbox rate exceeding 98%. This significantly reduces the risk of losing customers due to occasional undelivered emails caused by Email Sending IPs blacklisting. Additionally, Amazon SES offers relatively basic data analytics compared to AotSend, lacks global intelligent acceleration, and does not support automatic variables. AotSend Transactional email api excels in these areas, providing more robust features and capabilities.

Regarding API email delivery rate and inbox rate

Many customers have insufficient understanding of email delivery rates and inbox rates with email sending APIs. The following content on email delivery interfaces may be helpful.

3 Q&A

Based on real customer data, AotSend Transactional Email Provider delivery rate exceeds 99% (excluding failures due to non-technical reasons like formatting errors, full mailboxes, and non-existent email addresses). Our high email delivery rate is attributed to our meticulous design of trigger email scenarios and rigorous maintenance of email templates within the AotSend Email API Platform. AotSend imposes restrictions in four key areas: sending IP, sending email address, email type, and email content, which collectively enhance email delivery effectiveness. Furthermore, AotSend utilizes a carefully selected high-reputation IP pool dedicated solely to trigger-based emails. This strategy encourages a positive feedback loop where higher delivery rates lead to increased IP reputation. As IP reputation improves, email delivery rates also rise, creating a stable and high-quality environment for our Email Sending API Platform.

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 email 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 sending volume and the email content (Optimizing email subject and content to improve inbox rate). It's important to note that new domains typically lack email sending reputation and a good sending history, which may result in emails being delivered into spam folders initially due to not being whitelisted by recipient's 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' mailbox inboxes. With continued stable email sending practices, both email delivery and inbox rates will improve. Customers should not be concerned about this process.

For the AotSend Transactional Email Provider Service, improving email delivery and inbox 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 Domains and 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 email 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 Platform judiciously and appropriately to diversify email template content helps boost inbox placement rates effectively.

Customer Reviews

Real customer feedback from users of the AotSend Email API Provider

"I switched to a new OTP email API service provider because I was unsatisfied with the delivery rate of Amazon SES emails. Upon discovering this well-crafted website, I decided to set up the API for testing verification code email and 2FA email. After trying it out, we were very pleased. The system supports automatic deletion of records after 7 days, alleviating privacy concerns. Additionally, its data analytics capabilities are much stronger compared to Amazon SES. I promptly arranged for our technical team to integrate the AotSend Transactional email API service. We've been using it for over 2 months now and are extremely satisfied!"

"Previously, we used Email SMTP API for website email delivery, but we weren't satisfied with the delivery and inbox rates. We often received feedback from customers that they couldn't receive emails such as verification, reminder, confirmation, and notification emails. After finding this new service provider, we haven't had any more issues with customers not receiving emails. AotSend has excellent product quality, affordable pricing, and is an outstanding product that we plan to use long-term. AOTsend Transactional Email Service Highly recommended!"
