Essential for bulk emailing: global mailbox detection + effective address screening techniques

Anyone who has done email marketing knows thatThe biggest fear is not that no one reads the content, but that the email is not delivered at all. Many companies spend a lot of manpower and resources preparing mass mailing plans, but in the end they find that the click rate is almost zero, bounce emails pile up, and accounts are banned by the platform. The reason is often not that the content of the email is not good, but that the email address itself is unreliable.

want every time Email Mass mail allThe key to "implementation with sound" is to complete it in advanceGlobal mailbox detection and screening work, clean out invalid addresses and retain mailboxes that are truly reachable and convertible.

There is no filtering in the mailbox, and mass sending is gambling.

Many people are used to collecting email addresses from various channels: registration forms, sweepstakes, crawler tools, online and offline activities, but the quality of these addresses varies. If used directly without cleaning, the consequences are often:

lThe email bounce rate was abnormally high and the system demoted the email.

lThe domain name was blacklisted by the email service provider

lThe bulk sending platform banned the sending account, resulting in subsequent inoperability.

lDelivery costs are largely consumed by invalid mailboxes

lStatistical distortion of click-through rates and conversion rates can mislead decision-making

These problems can still be controlled in the domestic market, but once they enter the global market, the complexity of cross-language, cross-service provider, and cross-country email structures increases dramatically.Sending in bulk without checking the email address is basically equivalent to blind submission.

what is"Global mailbox detection"?

To put it simply, it uses technical means to comprehensively evaluate the email address and determine whether it:

lYes or noreal existence

lYes or noThe server is willing to receive

lYes or noActively available rather than one-time

lYes or noHave sending value

This is not simply looking at"Is the format correct?" Instead, you need to connect to the server of the target mailbox, observe its return signal, and make a scoring judgment based on behavioral data.

What are the filtering criteria for valid addresses?

An email address that is truly worthy of mass mailing usually has the following characteristics:

lThe address format is standardized and there are no spelling or symbol errors.

lNon-temporary mailbox or one-time platform generation

lExists on an active mailbox server and responds normally

lNo blocking, rejecting or blacklisting rules are set

lHave certain usage traces or behavioral activity

Whether the mail can be delivered successfully?80% depends on these basic elements. If these are not met, no matter how strong the promotional message is, it will be in vain.

Common Mistakes to Avoid When Testing Your Email

Misunderstanding 1: Only look at the email format

"Looks right" doesn't mean "it actually works." Just because an address looks like a mailbox doesn't necessarily mean it exists.

Misunderstanding 2: The system platform’s own detection is enough

Many mass email platforms only check whether the format is legal and will not help you determine whether the email address actually exists.

Misunderstanding 3: Try sending once and then check the bounce rate

This approach is extremely risky. A failed mass sending will lead to a decline in the reputation of the entire sending system, and the recovery cost is much higher than the initial cleaning cost.

Misunderstanding 4: Just test it once and use it with confidence

Email data is dynamic, and just because it is available today does not mean it will still be valid three months later. It is recommended to review and maintain regularly.
