Optimize your mailbox for better deliverability

Send emails via API for higher open rates

Increase your average open rates by 15% by sending emails through the Gmail API instead of SMTP. This method enhances deliverability and reduces the risk of landing in spam folders.

Set custom sending limits per mailbox

Control the maximum number of emails sent per day and per minute from each mailbox, preventing over-sending and maintaining a healthy sender reputation.

Customize delays between emails

Adjust the delay between email sends to avoid spam flags. Choose a fixed delay or set a range for random delays to mimic natural sending patterns and improve deliverability.

Match email providers for compatibility

Enhance compatibility by matching the sender’s and receiver’s email providers, ensuring better inbox placement.

Use branded links and custom tracking URLs

Maintain your brand identity with custom tracking URLs. Replace Reply’s default domains with your own to track opens, clicks, and opt-outs more seamlessly.

Send plain text emails for higher deliverability

Opt for plain text emails by removing all HTML, images, and tracking links. This can improve deliverability and open rates, especially for high-volume senders, though it limits tracking capabilities.

Enable List-Unsubscribe header

Add a List-Unsubscribe header to provide recipients with an easy way to opt out, meeting regulatory requirements and protecting your domain’s email deliverability.
