Google and Yahoo introduced stricter sender requirements for bulk email senders in 2024. These requirements are now part of normal deliverability best practice for anyone sending marketing or subscribed messages at scale.
If you send campaigns through Mailcamp, use this checklist to make sure your sender domain, campaign setup, unsubscribe process, and list quality are ready for Gmail, Yahoo, AOL, and related inbox providers.
Use this checklist if you send marketing campaigns to Gmail, Yahoo, AOL, or Google Workspace recipients.
Use this checklist if you send a high volume of email from the same domain.
Use this checklist if your campaigns are being rejected, rate limited, delivered to spam, or showing higher bounce and complaint rates.
Even if you send lower volume, following these requirements can improve sender trust and long-term deliverability.
Use a sender email address from a domain you own, such as [email protected].
Avoid sending marketing campaigns from public mailbox domains such as Gmail, Yahoo, Outlook, or similar consumer mailbox domains.
In Mailcamp, go to Sending domains and add your domain.
Use an email address from an active verified sending domain as your campaign From email.
If your plan does not allow custom sending domains, upgrade your plan before sending important high-volume campaigns.
Add the DNS records generated by Mailcamp for the sending domain.
Set up DKIM so Mailcamp can sign emails sent from your domain.
Set up SPF so your domain authorizes the mail servers used to send your campaigns.
Set up DMARC for the sending domain. A policy of p=none is the minimum starting point for many sender requirements.
Return to Mailcamp and click Verify Now after DNS records have propagated.
Make sure the visible From email uses the same domain you authenticated in Mailcamp.
Use a From name that subscribers recognize.
Avoid changing sender domains frequently, because consistent sender identity helps mailbox providers understand your mail.
If Mailcamp falls back to a default sender address, check whether your custom sending domain is active and verified.
Include a clear unsubscribe link in every marketing campaign.
Do not hide, remove, or make the unsubscribe link difficult to find.
Make sure your unsubscribe page and unsubscribe success page work correctly.
Honor unsubscribe requests quickly and avoid sending marketing emails to unsubscribed contacts.
Before sending, confirm that your email content includes the required unsubscribe tag or link used by Mailcamp.
Send only to people who opted in or have a clear relationship with your brand.
Do not use purchased, rented, scraped, or outdated lists.
Segment your audience so subscribers receive relevant content.
Clean bounced, invalid, inactive, and unengaged contacts regularly.
Monitor unsubscribes, complaints, and bounce reports after every campaign.
Use subject lines that accurately match the email content.
Avoid misleading sender names, fake replies, deceptive urgency, or unrelated promotional content.
Balance images with real text content.
Avoid excessive links, URL shorteners, and suspicious redirects.
Send test emails before sending to a full audience.
Set up a custom tracking domain when your plan supports it.
Use Mailcamp reports to monitor opens, clicks, bounces, unsubscribes, and spam feedback.
Watch for sudden spikes in bounce rate or complaint rate.
If Gmail delivery is important for your volume, use Google Postmaster Tools to monitor sender reputation and spam rate for your domain.
Gmail or Yahoo rejects your campaign: check DKIM, SPF, DMARC, From domain alignment, and unsubscribe requirements.
Your domain is still pending in Mailcamp: review the DNS records in Sending domains, wait for propagation, then click Verify Now.
Your emails go to spam: review authentication, list quality, complaint rate, campaign content, and sending consistency.
Unsubscribe errors appear before sending: add the required unsubscribe link or tag to the campaign content.
Complaint rate is high: pause broad sends, clean the list, and send only to recently engaged subscribers.
