How to choose an overseas email filtering tool? Invalid email addresses, duplicate data and customer sources must be processed

Just because there are email addresses in overseas customer information does not mean that these data can be directly developed. During actual sorting, we often encounter email format errors, duplicate addresses, no updates for a long time, and the same customer repeatedly leaving information on different channels.

Really practical overseas mailbox screening, not justPick out the "emails that seem to have problems", and more importantly, retain the source of customers, product requirements and other contact information so that subsequent development can still take over.

The most common problem with overseas email lists is not just the wrong email address

The sources of overseas customer data are usually complex.

Official website inquiries, exhibition materials, advertising forms, member registrations, historical orders, and customer service records may all leave email addresses. After different channels are combined for a long time, it is easy for a customer to be repeated multiple times, the email fields are not consistent, and even the same company leaves multiple contact email addresses.

More common questions include:

lThe email format is obviously incomplete;

lThe same email address appears repeatedly;

lThe same customer has used multiple email addresses;

lCompany email and personal email are mixed together;

lThe address left long ago has not been updated;

lThe email address is still there, but I don’t know why the customer left it in the first place.

Therefore, when organizing overseas mailboxes, you cannot just focus on the mailbox column.

Mailbox deduplication can be done, but customer history should not be deleted at the same time.

The same customer may first leave an email address through an advertisement, then inquire from the official website, and then enter again after the final transaction is completed.CRM.

If you only look at the email field, this person may appear two or three times.

A more appropriate way to remove duplicates is to merge duplicate contact information but retain the original business history. For example, where the customer came from for the first time, what they consulted, whether there was a quotation, and whether the transaction was completed later, this information is more valuable than a single email address.

The simple understanding is:

Mailboxes can be merged, but customer relationships cannot be deleted.

In this way, when you develop old customers again later, you will at least know what topics to start with, instead of just leaving a list of email addresses.

Business email and personal email have completely different usage scenarios.

DoWhen developing B2B customers, corporate email is usually easier to match the company background.

For example, if a customer uses a company domain name email address, and the original information also contains the company name, position, and product requirements, this type of clue will be relatively complete.

Personal email is not without value.

Some small and medium-sized customers, self-employed people or early inquiries will already use it.Gmail, Outlook and other personal mailboxes. What really determines whether it is worth continuing to follow up is whether the customer has the true source and business needs, rather than directly reducing the value when seeing a personal email address.

Therefore, the email type can be used as auxiliary information, but it cannot replace customer judgment.

After filtering the email, we also need to look at why this customer appears on the list.

The business value of two mailboxes with the same normal format may be very different.

One customer just submitted a product inquiry yesterday, another customer attended the event three years ago and has had no interaction since.

If you only look at the mailbox, both data are fine; if you put it in the sales follow-up, the priority is obviously different.

Therefore, after organizing the overseas email list, it is best to continue to retain this information:

where customers come from;

Which country or market it belongs to;

What products have been consulted;

When was the last interaction;

Are there any historical orders?

It is currently in the new inquiry, quotation, old customer or silent stage.

These are the real basis for determining how to contact us in the future.

Only email is not enough, customer contact information can continue to be completed

In addition to email addresses, many overseas customer information also saves mobile phone numbers.

In this case, after the mailbox is sorted, you can continue to use the mobile phone number as another customer portal. Digital Planet can help existing customer numbers organize international numbers and continue screening based on actual business needs.WhatsApp, Telegram, LINE, Zalo and other corresponding social platform account status.

For example aThe B2B customer originally only inquired through email, but at the same time took the initiative to leave his mobile phone number, so that he could later confirm whether this number has a WhatsApp or Telegram account basis.

In this way, customer information no longer has only one email address.

However, after detecting a social account, it does not mean that the customer's original communication habits must be forcibly changed. Customers who have been communicating normally through email in the past can still use email first; social accounts are more suitable as supplementary channels or backup entrances after the original contact information becomes invalid.

My email is normal, but I can’t call directly."Quality Customers"

The email format is correct and the contact information is complete, which only means that the data foundation is better.

Real high-quality customers also depend on whether there have been actual business actions recently.

For example:

Recent active inquiry;

Already entered the quotation stage;

Historical customers re-consult;

Enter the normal repurchase cycle soon;

Recently responded to sales or customer service.

These actions are closer to real opportunities than just a valid email address.

On the contrary, even if an email is completely normal, but the source is unclear and there has been no interaction for several years, there is no need to"Email is available" will send development content frequently.

After sorting out your email list, it’s best to continue stratifying your customers.

If an overseas email list ends up with tens of thousands of addresses put together, the value of screening has not been fully realized.

It can be simply divided into several categories according to business status:

Recent inquiries from customers

Prioritize responses to product, pricing, and delivery questions.

Already quoted customers

Continue to follow up on quotation feedback and purchasing plans.

Historical transaction customers

Focus on repurchase, new products, after-sales and long-term maintenance.

Long term silent customer

Reduce the frequency of contact and activate again when there are new products, price changes or other reasonable reasons.

Customers who explicitly decline to continue marketing

Stop active promotion.

In this way, when you send subsequent emails or switch to other communication channels, the content and rhythm will be more consistent.

What overseas mailbox screening really wants to leave is"Customer data that can be developed further"

Email screening is not about getting one at the end"Normal email list", but makes it easier for the original overseas customer data to continue to be used.
