If you are not receiving emails sent through Mailcamp, the cause is usually related to campaign status, recipient status, sender authentication, inbox filtering, or delivery restrictions from the receiving mailbox provider.
Use the checklist below to narrow down whether the email was not sent, was skipped, bounced, filtered to another folder, or delayed by the recipient's mail server.
Open the campaign in Mailcamp and check its current status.
Confirm that the campaign is not still a draft.
Confirm that the campaign is not scheduled for a future date or time.
If the campaign was paused or blocked because of account limits or deliverability restrictions, resolve that issue before sending again.
Check the campaign report after sending to confirm that delivery processing started.
Open the audience/list used by the campaign.
Search for the email address that did not receive the campaign.
Confirm that the contact is subscribed.
If the contact is unconfirmed, they may need to confirm their subscription first.
If the contact is unsubscribed, bounced, blacklisted, or suppressed, Mailcamp should not send marketing emails to that address.
Confirm that the contact is included in the selected list or segment for the campaign.
Open the sent campaign report.
Review the delivery summary.
Check the bounce report to see whether the mailbox rejected the email.
Check the unsubscribe report to confirm the contact did not opt out before the campaign.
Check feedback or complaint data if available for the campaign.
If the email appears delivered but is not in the inbox, check spam, promotions, updates, and other filtered folders.
Use a From email that matches an active verified sending domain.
Go to Sending domains and confirm that the domain is active.
Review DKIM, SPF, and DMARC records if the domain is pending or recently changed.
If Mailcamp falls back to a default sender address, check whether your custom sending domain is available for your plan and properly verified.
Use a recognizable From name so recipients and mailbox providers can identify your messages.
Search the inbox for the campaign subject, From name, or sender email.
Check spam, junk, promotions, updates, and quarantine folders.
If the recipient uses a company email account, ask them to check with their IT or mail administrator.
Ask the recipient to allowlist your sender address or domain if their organization filters marketing email aggressively.
Remember that Gmail, Yahoo, Outlook, and corporate mail servers can place the same campaign in different folders for different recipients.
Make sure the subject line accurately matches the email content.
Avoid misleading sender names, suspicious links, URL shorteners, and excessive sales language.
Balance images with readable text content.
Keep the unsubscribe link visible and working.
Send a test email before sending the campaign to the full audience.
Check the test recipient's spam, promotions, and quarantine folders.
Confirm that the test address was typed correctly.
Try sending the test to a different mailbox provider to compare behavior.
Check whether your company mail server blocks test messages from marketing platforms.
If the test email contains placeholder links or sample unsubscribe links, remember that it may behave differently from a real campaign sent to subscribers.
The campaign has no recipients: check the selected list, segment, and subscriber status.
The email bounced: review the bounce log for the reason returned by the recipient mail server.
The email is in spam: review sender authentication, content quality, list quality, and complaint history.
The email is in Promotions: this is inbox categorization, not a delivery failure.
The contact was skipped: check whether the address is unsubscribed, unconfirmed, bounced, blacklisted, or outside the selected segment.
Delivery is delayed: wait and check again later, because some mailbox providers defer or throttle email before final delivery.
