Why are my contacts inactive

Spam Filters: Email service providers have strong spam filters to protect their users from unsolicited emails. If your emails appear to be spammy (e.g., by having all-caps subject lines, lots of exclamation points, spam trigger words), they may end up in the spam or junk folder instead of the inbox.

Email List Quality: If your email list contains a lot of invalid or outdated email addresses, those emails will bounce back and won't be received. It's important to keep your email list clean and up-to-date.

Email Format: If your emails are not properly formatted or have broken or inappropriate content (like heavy images, broken links, or HTML errors), they may not be delivered successfully.

IP Reputation: If your IP address has been flagged for sending spam or if you're sending from a new IP address that doesn't have a reputation yet, ISPs (Internet Service Providers) might block your emails.

Email Authentication: If you're not using email authentication protocols like DKIM, SPF, and DMARC, ISPs might not deliver your emails. These protocols help verify that your emails are actually coming from you and not a malicious actor.

ISP Blocking: Some ISPs might block or limit emails coming from certain servers if they believe those servers are sending spam. This is especially common if you're sending a lot of emails at once.

Low Engagement: If your previous emails have had low engagement (i.e., few opens or clicks), ISPs might start delivering your emails to the spam folder. They do this because they think their users are not interested in your emails.

Unsubscribed or Opted Out: If users have unsubscribed from your email list or previously marked your emails as spam, they will not receive your future emails.

Legal Compliance: If you're not complying with email marketing laws like CAN-SPAM in the US, GDPR in Europe, etc., your emails might be blocked or filtered out.
