# How do I make sure my emails will get delivered?

There’s no system that can precisely tell which emails reach a lead’s inbox or go to spam, mainly due to privacy, security, and technical limitations.

Humanic improves deliverability by gradually increasing your send rate, helping you avoid spam triggers, skipping contacts who haven’t opened multiple emails, and ensuring every message includes an unsubscribe option.

Ultimately, deliverability can only be estimated based on a few key factors:

* Only emailing people who have opted in.
* Regularly cleaning your list to remove invalid or outdated addresses.
* Sending content that’s relevant to your audience.
* Avoiding purchased or scraped email lists.
* Your domain’s age and reputation.
* The sender IP’s reputation.
* Correct setup of SPF, DKIM, and DMARC.
* The presence of links, images, or tracking pixels in your emails.

**More tips to increase deliverability**

* Keep your emails relevant and valuable to your audience.
* Write honest subject lines that match your message and avoid clickbait.
* Always include an easy-to-find unsubscribe option or let people know they can reply to unsubscribe.
* Regularly clean your list to remove inactive or invalid contacts.
* Test different versions of your emails and track results to improve performance.
* Use a trusted email service provider with strong deliverability tools.
