Check Email Deliverability with a Free Email Spam Test

1. 1

   Choose how you send

   Pick the tab that matches how you send your emails — from an email account, from a marketing system, or by API request. Use the same method you plan to use for the real campaign.

2. 2

   Send a spam test email

   Copy the supplied test addresses and send your campaign email from your mailbox or ESP. Use your usual subject line, body, links, and sending setup.

3. 3

   Open your report

   Results usually arrive within minutes. Some providers take longer, so wait to receive all the results before drawing early conclusions.

1

Authentication

Incorrect settings can cause emails to get rejected or sent to spam. Check your SPF record, DKIM setup, and DMARC policy. Adeline can help find alignment failures with DMARC monitoring.

2

Reputation and volume

Sudden sending spikes can trigger spam filtering (especially on newer domains). To avoid this, increase volume gradually, automate email warm-up with Adeline, or use a quality seed list.

3

Content

Messages with misleading subjects or suspicious links often get filtered or spam-reported. Match your subject line to the message, check links, and test your template.

4

List quality

Invalid addresses cause bounces, and poor targeting can generate spam complaints. Verify your lists, remove invalid addresses, and stop sending to unsubscribed recipients.

5

Blacklists

A listed sending IP can cause rejection or spam placement. Work with your sending provider to resolve the underlying problem before requesting delisting.

Addressing these issues can improve your chances of reaching inboxes, but no single fix guarantees inbox placement.
