The importance of email marketing and databases in e-commerce
Before we tell you why you should include this powerful sales channel in your digital strategy, let's start with a brief introduction for those of you who haven't taken full advantage of this channel or associate it with spam.
What is email marketing?

Email marketing is the use of email to promote products or services. Email marketing is the use of email to develop relationships with potential customers or clients. A channel of communication between a sender and a receiver to promote or develop relationships of interest, whether commercial, informational or otherwise.
Why is email marketing so important for e-commerce?
This communication channel has the advantage that it is not just a channel for large companies or one that requires large investments. It can be used by all types of companies regardless of their size.
Reasons why you should have this channel as part of your digital strategy:
- Accessible channel for any type of business
Many companies have the misconception that email marketing is a channel that can only be used by large companies, as they have to make large investments in email sending platforms, designers, layout designers with knowledge of html, etc ...

- Helps you get in touch with your audience and customers
It allows you to keep in touch with customers or potential customers who at a certain point in time were interested in services or products. When they subscribed to your database, they gave you permission to keep sending them information relevant to them. Email marketing serves to open an important channel of communication with these subscribers, being in the "top of mind" (that brand that occupies the first place in the memory of a person when they think of a certain product or service).
It will allow us to be in direct contact whenever there are new promotions or changes in our business.
- Campaigns tailored to your target
One of the biggest mistakes that companies make is sending the same email to their entire database. Do you wonder why this is a mistake? Well, simply because each person is in a different moment of purchase. Does a subscriber who was looking for information about a product "A" and we send offers on product "B" have the same possibility of buying? or... The one who entered looking for product "B" but there was no stock and now we send him a promotional offer for product "B"?
To give an even clearer example, a man will not be a good target when we want to send an email with an offer for push-up bras!
Take advantage of database segmentation. Not all subscribers are the same, nor are they at the same point of purchase... or even repurchase.
Basic segmentation:
- Inactive customersThose who have not carried out any transaction with us within a defined period of time.
- Potential customersThose who have never bought to date.
- New customersThose who have just completed their first transaction.
- Loyal customersThose customers who have made "x" transactions in a period of time defined by us.
- Contact your subscribers in real time
Nowadays most of us have our email on our smartphone, updated in real time, which allows communication with potential customers or clients, in real time. Subscribers will be able to respond in a short time to our offers or promotions.
Imagine the potential of getting in touch with a potential customer with flash sales (discounts or promotions offered that expire within a limited period of time).
- Emails are more personal than other contact messages on the internet.
The emails we receive are more personal, thanks to automation, when a person subscribes to our database, they leave us all the information such as email, names, or date of birth... With email marketing platforms we can address someone personally, by name, or even on their birthday, making communication much more personal and close, far from the advertising impacts such as Facebook or Google Ads.
- Ease in analysing results
A very important tool, as it will allow us to have valuable information in a short period of time such as; conversion rates, click-through rates, subscription rates, email open rates and many other metrics that you can consult in our post of the 5 essential metrics of the new email marketing
In email marketing sales can be tracked, so it is essential to evaluate each campaign we do, being able to obtain the ROI (return on investment value of a campaign).
- Email marketing automation
Email marketing automation will make your life easier and simplify sending to your subscribers, it is a powerful tool that also creates a bond with the recipient.
What is email marketing automation?

Email marketing automation is the automation of email marketing actions. Being able to automate certain processes such as; sending emails, generating automatic segments, creating a database, using new templates, etc. ....

- An excellent loyalty channel
Many people think why they have to build customer loyalty or waste time with these people if they are already customers... It is a huge mistake to think that a company's strategy should be based solely on attracting customers. Building customer loyalty is going to give us a greater return on investment.
Reasons why loyalty is not an option, but an obligation for companies:
- In the digital channel, acquiring a new customer is 5 to 10 times more expensive than building customer loyalty.
- A customer's LTV increases as they stay loyal to the company for longer and make higher value purchases.
- It is possible to allocate more CAC (Cost of Customer Acquisition) if we extend the LTV, even if we lose money on the first purchase, we can make it profitable in the long term with a good loyalty strategy.
- A loyal and satisfied customer will recommend us both to their closest circle and on social networks.
- Users who become customers, after making their first purchase, have a 27% chance of buying again from the same e-commerce site. In addition, if that customer makes a second purchase, they have up to a 45% chance of making a third purchase.
- A loyal customer spends 67% more within e-commerce than a new customer.
The benefits of email marketing as a loyalty strategy:
- Very low costIt allows us to target our customers and reach thousands of users at a very low cost.
- VersatilityWe can contact you personally (using names and surnames), using a variety of formats, from videos to classic text.
- AutomationAs we have already mentioned, we can get in touch in an automatic and personalised way. We can send from personalised offers to birthday greetings (something that will easily distinguish us from the competition with a simple automatic email).
- Bidirectionality: The customer has this channel to contact us, it is an open channel of communication in real time (being able to use the channel as customer service to provide better service).
- We create brandBy sending newsletters, personalised offers and content strategies, we can always be at the top of our customer's mind. Avoiding infidelity with other brands.

Don't have a database in your e-commerce?
Not all e-commerce companies have a clear digital strategy from the start, often over time is when you start to analyse the data and create a digital strategy. In case you want to start with email marketing as part of your new digital strategy, but you do not have a database or you want to expand your database, you can turn to professional companies such as CoRegisterswho will capture the database you need to carry out your digital strategy.
Databases are the fuel of e-commerce, for that reason it is very important to have quality databases, which are standardised (cleaning and filtering process to eliminate false mails or mails with erroneous characters) and which have been obtained in compliance with the laws in force.
Databases captured from a specific sector such as "insurance" will not be useful if your business sells "nappies", for this reason, go to professionals in the sector, who will be able to advise you and capture the specific database for your business.

A database is the collection of all the data of your customers or potential customers, so it is very useful to be able to segment as we have already seen. Run campaigns to specific segments, send information of interest to each segment. Not all customers are at the same point in the buying process, nor are they looking for the same product or service.
How can you improve your email marketing?
If you have reached this point, dear reader, you have seen the potential of this channel. Here is a list of tips so that you can start to become an email marketing crack:
- Not being a spammer
Some companies think that their objective is to bombard their customers or potential customers with mails that do not provide any kind of value. This creates the opposite effect as they associate the brand with spam. With the consequence that if many people mark a company's email as spam, it will be considered as spam in the ESP (Email Service Provider), preventing us from going back into the inbox.
- Your audience is special (build loyalty)
We've said it time and time again, we won't tire of repeating it. Make your subscribers and customers feel special. Congratulate them on Christmas, New Year, their birthday, etc... address them personally with their name, ask them what they thought of their purchase once they have received the product, encourage them to share their reviews, solve any problems they have with a "10" customer service and if they have had problems, solve them quickly and with the least inconvenience for the customer and even provide a discount or compensation on their next purchase.
Remember, acquiring a new customer costs 5 to 10 times more and spends less than a loyal customer.
- Do A/B Testing
Often what we think is logical is not what works best, so always analyse and test your campaigns. A simple subject line can make all the difference in getting completely different results.
During the US elections with Barak Obama, during fundraising, testing different issues, they saw that issue "A" generated 403,600$, while issue "B" generated 2,540,866$.
- Segment your subscribers and users
As we have said, you should not send the same type of email to potential customers as to inactive ones. For some, we will try to get them to make their first purchase through discounts or promotions, while for others, we will try to get them to open the email with a subject line that catches their attention.
