Dont send email from free email providers
These types of providers have adopted a DMARC policy that tells email inbox providers to reject any emails that don’t have the proper technical signatures.
For example, if you’re sending an email with a gmail address through a third-party software like emailidea.biz, and outside of the gmail framework, your message will be rejected. This is done to prevent phishing scams and other types of attacks using the gmail domain. So dont send email from free email providers like gmail.com, yahoo.com, hotmail.com
Note: Starting in February 2024, Gmail and Yahoo will enforce a custom authentication and require a published DMARC record for anyone sending over 5,000 emails to their addresses within 24 hours. To avoid email bounces, we highly recommend you authenticate your email domain and set up DMARC.
Additionally, if you use a free email service like Gmail or Yahoo as your From email address, we strongly advise switching to an email address from a private domain, such as the one you use for work or your website.
Why this happen
The service provider would just set the from address to the client email address and send the email. This email can be hosted on the client domain or it might be an gmail.com or yahoo.com address. But there is a big problem with this functionlity because it is going to spam or bounce while we are using best Internet service provider
Purchase a Domain
You can purchase your registered domain in your email, and on your website. You can create email address and make DKIM and SPF setting in your domain panel. This helps make your entire online presence more recognizable to your audience and may improve delivery of your email campaigns.
If you are sending from gmail.com, yahoo.com, or some other third party domain that neither you nor the customer on whose behalf you’d like to send control, We have bad news. You are going to have to find a new way. Starting very soon, those messages are never going to get delivered. Both Google and Microsoft are planning to implement this policy very soon, and Yahoo has already made the change.
We don’t know when the Gmail and Microsoft will officially stop allowing third-party sending without domain control, it is best to prepare to keep your delivery rates as high as possible. For more insight on how to reach the inbox, check out our Interactive Email Deliverability Guide.
