Summary
Gmail presents several limitations for both sending and receiving emails, particularly concerning high volumes and time-sensitive communications. These limitations encompass hourly and daily sending limits, potential deliverability issues, the risk of account restrictions, and possible delays in email delivery. These restrictions stem from Google's need to maintain system efficiency and prevent spam. To overcome these challenges, experts and documentation suggest alternatives like dedicated SMTP services (e.g., Amazon SES, Sendgrid, Mailgun), transactional email services, self-hosted servers, and professional email marketing platforms. These alternatives offer better control, scalability, and reliability, although some require more technical expertise. Furthermore, using a professional email service with its own domain can significantly improve deliverability and brand reputation.
Key findings
- Gmail Limitations: Gmail has limitations on hourly/daily sending, can defer emails, and isn't designed for mass marketing.
- Deliverability Issues: Gmail's limitations can lead to deliverability issues and a higher risk of being marked as spam.
- Sending Alternatives: Dedicated SMTP services, transactional services, self-hosting, and marketing platforms offer alternatives for overcoming Gmail limitations.
- Time Sensitivity: Standard email protocols don't guarantee timely delivery; delays can occur for extended periods.

Key considerations
