E-Mail Marketing

Please pay attention to our SPAM prevention policy and recommendations for bulk emails to get the best results while avoiding the risk of sending SPAM.

Bulk e-mails sent to clients

Bulk sending of “requested” emails are routinely supported and we offer a reliable and powerful environment. Many of our clients communicate effectively with tens of thousands of their customers.

  • Newsletters
  • Competitions
  • Info-Service (course movements, goods status, etc.)
  • Product offerings
  • Watching dogs
  • and another legitimate email marketing

However, we do not allow to send SPAM!

What is a SPAM

SPAM is an unsolicited and harassing message that is most often sent in bulk for the purpose of bidding, branding or promotions, and also for frauds and virus spreads. SPAM can take the form of emails, posts in discussion forums, online comments, etc.

Why are we avoiding SPAM?

SPAM is a global problem that harms the recipient, overloads network providers, makes communication difficult, and make damages.

  • We protect our network and IP addresses from penalizing and blocking by other e-mail service providers (e.g., Google, Yahoo, etc.).
  • We ensure reliable and fast delivery of legitimate emails of our clients.
  • We limit the possibility of spamming our sites and our clients’ computers.

What is a business or marketing message

Sending of bulk Business or Advertising messages

The commercial message may be sent in electronic form only with the prior consent of the recipient.

The exception is communication with existing customers. For example with recipients whose contact you have previously received in connection with the sale of a product or service (in sales or sales negotiations) and you are sending a notice about your own similar products or services.

The law prohibits the sending of commercial communications electronically if:

  • is not clearly identified as a commercial communication,
  • hides or conceals the identity of the sender whose name the communication is made to,
  • is sent without a valid address to which the addressee could directly send information that he does not wish the business information to continue to be sent to him by the sender, free of charge or at the sender’s own expense.
Prohibited bulk business emails

Purchased e-mail databases

The law prohibits the use of such data. You must obtain the consent of the recipients directly in relation to the sender (ie you) and the known purpose, ie the product or service, to which the recipient must give informed approval.

In addition to the transfer of consent, the technical area of the contact databases being sold is also problematic:

  • The seller must allow the recipients to withdraw consent at any time (ie even after the sale of the database, each contact must be excluded from all the databases already sold at the request of the recipient).
  • The recipient has to know for sure to whom he agrees – are you able to verify that the seller’s rules were clear to the recipient at the time of obtaining the consent?
  • Do you know about the recipient’s contact with the date, time, and URL where the consent was obtained?

Getting approval by e-mail

This form prohibits the law because the e-mail greetings itself is a direct or indirect sales support and commercial communication.

Obtaining consent by telephone, personally, through leaflets, etc., is not regulated and is considered to be the correct way of obtaining consent (ie the recipient itself shows interest in the communication in electronic form).

How we evaluate SPAM

We usually check SPAM when we detect a high number of sent emails and especially when we are notified about spam.

As spam we evaluate:

  • If we find a discrepancy with the legal requirements
  • If you are not in a position to provide credible proof of the recipient’s consent (you do not need to have the consent of the recipient if your existing customers are concerned and if you offer your own similar products or services)
  • Any other collective announcements where it can be clearly inferred that the consent of the recipients has not been obtained or of an annoying nature, links to non-functional or non-existent content, or any other attempt to circumvent the law
  • Any attempt to obscure the identity of the sender, server, etc. (eg non-existent address, change of headers, etc.)
  • Messages containing / referring to dangerous content (viruses, phishing, other malware, etc.)
  • Repeatedly undeliverable emails (non-functioning mailing addresses should be deleted immediately)

Consequences of sending SPAM

If you are considering sending SPAM, consider the damage that you may cause to yourself and others and the resulting consequences of legal liability.

  • You can permanently damage your customer relationships
  • You can degrade your own IP address
  • You can also degrade your own domain you send all correspondence from (eg clients or service providers mark your domain as a spammer)
  • You can cause damage to us as a provider, for example by blocking the IP range
  • Fines ranging from hundreds of thousands to millions of euros

As a provider we reserve the right to restrict or terminate the provision of services in the event of their misuse for the purpose of spamming in any form.

How to send bulk emails correctly

If you want to send emails correctly and minimize the risk of spamming, we recommend that you keep a few points:

Get the recipient’s approval first

  • You do not need if you communicate with existing customers or if the communication relates to your business and products or services that are similar to those previously purchased or interest by the customer.
  • The recipient consent must be obtained in advance and must be informed (eg on your presentation event, in the competition, etc.) and demonstrably clear who gave the consent, to whom (for you) and for what purpose he provided it.

E-Mails batching

  • Blocking SPAMs on receiving servers is usually a matter of the number of messages sent.
  • Spread your sending to a longer period. Do not try to send it as fast as you can, let your messages arrive rather slower than not at all..
  • A safe dosing is about 1,000 emails per hour, depending on the type of service/membership (refer to your membership FUP limits). If you are not sure or need to send more, do not hesitate to contact us.

Technical accuracy and specification

Technical errors are one of the main reasons why your messages are blocked or rejected by various antispam filters, so please follow these recommendations:

  • Always fill in correctly the data of the email headers, ie sender, subject, recipient
  • The sender’s address (ie the From header) must be from the domain on which the sending script is located
  • Use headers for bulk messages – Precedence: Bulk and List- (List-ID, List-Unsubscribe, etc.)
  • The content-to-image ratio should be balanced (emails containing images only are often referred to as SPAM)
  • Ensure the correct encoding of the email
  • Use an electronic signature, if its possible
  • Avoid bad words in the subject such as Link, Share, Sale, Best etc.
  • Avoid typing BIG CHARS
  • Do not start the e-mail with the word “Dear …”
  • Use SPF for your domain and sign emails with DKIM

Compliance with legal requirements

  • Always indicate clearly and comprehensibly that this is a commercial message (do not obliterate the message with unclear names)
  • Always state the sender/yourself clearly. If you are only a technical manager, never give a third person even when presenting its products or services (for example, if you recommend your partner’s products to your customers, you are still the sender)
  • Always allow the recipient to withdraw consent to the delivery (free of charge and effectively), and if you withdraw it, make sure you do not accidentally send the message again
  • The law does not apply to charitable and charity work, but it is still good to follow the rules of sending
