Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Nodemailer lacks built-in support for complex email functionalities such as DKIM signing, SPF validation, and DMARC reporting.
When sending a high volume of emails, Nodemailer may experience performance bottlenecks due to its sequential processing model without built-in load balancing or parallelism.
Setting up secure email transmission with TLS/SSL requires manual configuration and handling of certificates, which can be error-prone and complex for developers without extensive experience in email protocols.
