E-mails from Sweap are given above-average positive ratings and therefore have a low spam probability and high deliverability rate. Still, we receive occasional enquiries that e-mails configured and sent with Sweap do not reach the client.

There can be numerous reasons for this.

Basically, information technology tin be said that in that location are always two competing sides when sending due east-mails: Protection and security vs. the most comfortable use of an due east-mail inbox. Therefore, there are strict restrictions which must be met by an eastward-postal service in order to exist accepted and successfully delivered to the customer'south inbox.

In the following we have compiled an overview with possible reasons why east-mails practice non reach your customers. This article also contains a lot of information on how y'all can farther improve the inbox rate of your e-mails - the successful commitment of e-mails.

General Information

East-mails have become one of the about important means of advice in the 21st century. Whether orders, newsletters, bookings, ... almost everything is sent by e-mail present. Withal, according to a study past returnpath.com, in 2017 every fifth e-mail in Germany yet did non reach its intended recipient.

In full general, e-mails do non reach the recipient because they are declared as junk e-mail, i.e. spam, during the sending process.

The sending process of e-mails

In order to sympathise why an email sometimes does not accomplish the recipient, the path of an email should be explained in advance. In a simplified style, the way an email is sent can be compared to the way information technology is sent by post. In dissimilarity to sending an e-mail by post, the due east-mail service must pass several stages on its way to be delivered successfully.

Allow'south take a closer expect at the route of a Sweap east-mail:

E-mails that you have created with the Sweap templates and transport to your customers are sent via the e-mail service provider Mailjet. Sweap has a fixed IP address, which is therefore anchored to all e-mails sent via Sweap. Now the email tries to reach the customer with this IP accost. Still, it does not immediately land in the inbox, but simply at the client'south electronic mail server, also known as a gateway. If nosotros compare the sending process again with the sending of letters by post, we can say that the gateway is the forepart door of the client'south apartment or business firm, where the postman showtime has to ring the bell. Simply when the electronic mail has passed the gateway can it continue its journey to the recipient's e-mail clients. These are the email programs on your customers' computers. Examples of eastward-mail clients are Outlook, Apple Post or Lotus Mail. Once there, your electronic mail must exist moved from the due east-mail customer to the inbox.

This can be shortened: The east-mail is sent with a specific IP address, must first pass the gateway (due east-mail server) before it can make it at the e-mail client and ideally be transferred from at that place to the inbox.

However, the email is checked for security, maliciousness and trustworthiness during each stage of this process. This means that during each stage the electronic mail may get 'stuck' because information technology does not pass a check and thus may non continue its planned route to the client's inbox. lxx% of all unsuccessfully delivered e-mails are already blocked at the gateway. But fifty-fifty emails that laissez passer through the server are checked once again past spam filters and the email client itself for content, subscriber commitment and sender reputation.

What tin happen with my electronic mail on your mode to you / Tips and tricks for successful delivery

Sent east-mails are ever checked for their security and credibility. This ways that before an email arrives in the customer's mailbox, information technology goes through several stages of sending and is checked several times for its content and security every bit well as for spam suspicion. Checks are carried out by both the server and the customer, which in plow utilize common 'tools' such as spam filters and blacklists to cheque the spam relevance and security of an email.

Permit'due south take a look at the reasons why an email is not delivered to the client and clarify the possibilities to prevent this.

Due east-mail is stopped at the server (gateway)

Afterwards the sender has sent an electronic mail, it is quite possible that this east-mail does non get through to the server, i.e. cannot successfully laissez passer the gateway.

The following reasons can be the reason for the electronic mail being held up on the server:

The recipient server is not found because the server name no longer exists (hard bounciness)
Server is found and exists, but gives the feedback that the recipient electronic mail address does not (no longer) exist (hard bounce)
the e-mail service does not reach the server due to a soft bounce, i.e. a temporary error message such equally an overfilled mailbox or the temporary unavailability of the server
Eastward-post does not meet the server'due south spam criteria and is non put through due to this and due to firewall settings of the server. The nomenclature as untrustworthy tin can occur, for example, because the server does not all the same know the sender. Y'all should therefore always advise your customers to create the sender accost as a contact and to put their sender IP address on a permission list.
The sending address/domain or IP accost is on the internal blacklist of the e-mail server and thus the delivery of the e-mail is blocked.

For more information nearly difficult and soft bounce, see this article about the Email Log.

Determination: As a simplest solution, it is recommended that the IP address and/or shipping address of Sweap be stored with the server as secure. You should also make certain that the shipping address / domain or IP address is not on the server's internal blacklist (this includes the domain mailjet.com of our email provider).

If an e-mail is rejected past the server and its farther manual is blocked and stopped within this 'stage', the sender (here: Sweap) receives an error message that the email could not be delivered. An error bulletin is then displayed in the electronic mail log, which you can access in Sweap.

Since we send our e-mails via the e-mail service service provider Mailjet, the e-mail may be blocked by Mailjet due to further settings and may non reach the server. Mailjet preselects recipient email addresses and blocks certain ones. An e-mail accost is blocked by Mailjet if previous eastward-mails to this recipient have not arrived. Mailjet remembers this and so blocks the respective e-mail address (no more due east-mails are sent to this recipient). This is a simple protection machinery of Mailjet, as undeliverable emails damage the reputation. Past blocking these emails, Mailjet can annul a bad reputation. If a recipient'due south email accost has been blocked by Mailjet in the by, but is at present to be used again, y'all must request the unblocking to exist removed manually via Sweap.

E-mail passes the server without problems, but all the same does non achieve the inbox of the recipient

Even if the electronic mail passes through the gateway, this does not mean that it volition actually reach the server's inbox. After a successful bank check on the office of the gateway, the server puts the email through to the e-mail service client to check over again. The east-mail must "evidence" its trustworthiness once again here, because electronic mail clients also check e-mails for spam probability (using spam filters, blacklists, firewall and security settings, etc.). Accordingly, information technology can happen that an eastward-post is classified equally dubious, dangerous or damaged even in that location and therefore does non reach the recipient's inbox.

This is not e'er easy to empathise, because if an e-mail passes the server, information technology is noted in the due east-mail service log every bit successfully "delivered". Notwithstanding, the settings of the e-mail client tin can still ensure that the electronic mail does non arrive direct in the inbox, but instead ends up in the spam folder or in the 'Undefined' or 'Unknown' folder, for case, where information technology tin be disregarded past the recipient.

Only do what? There are numerous tips and tricks to ensure that your e-mails really exercise reach your customers successfully. We take compiled the nigh of import help for yous here:

The well-nigh important matter to kickoff with: Brand sure you have a good reputation as a sender and maintain it continuously, because your sending reputation is not only checked by the server, but also by the client.

A proficient reputation increases the deliverability of your eastward-mails. Reputation is comparable to the credit rating bureau (Schufa) information from banks. However, since this is a rather detailed signal, nosotros will deal with information technology again separately later.

Use a known sender e-postal service address (including a unique sender name) and try to ensure that it is listed equally a contact in your customers' address book.

Avoid spammer behaviour and suspicious east-mails (correct HTML code of your e-mails)

Your highest priority when sending e-mails should be to avoid classifying your e-mails as spam. Therefore, please annotation that you lot should definitely avoid spammer behaviour. Thus, when you create your east-mails, you already make up one's mind how high the probability is that they will be classified as suspicious spam. On the one manus, this concerns the content of your due east-mails. In general, the content should be rubber and properly formatted (pay attention to metadata, e-mail structure and formatting peculiarities). On the other hand, the sending rate per se must besides exist considered. If y'all have been sending an average of 50 e-mails per day from your electronic mail address, and you noticeably increment this rate in a short time, spam filters or like will take this equally suspicious. On the content side, it should be noted that the e-mail templates of Sweap are designed in such a way that they have a very low spam probability. Nevertheless, we take put together a list of tips and tricks for you to consider in guild to reduce the spam probability of your e-mails.

Pay attention to positive domain authentication using DKIM and SPF values

These are values that are stored when you are registered as a shipper. This happens, for example, when yous create a new sender east-mail service address. These values are used to demonstrate to the electronic mail client that the sender e-mail address is actually legitimate.

In unproblematic terms, this means that the SPF record allows you to verify the authenticity of the server and tin help prevent phishing and identify you lot every bit a legitimate sender. These values establish a link between the actual web page and the domain name used in the sender accost.

The DKIM values, on the other hand, provide your email with a unique signature that tin be used by the receiving server and email customer to verify that the email actually comes from the specified source.

Delight note that Sweap takes care of creating DKIM and SPF values when you have us set a new sender email address.

Another electronic mail validation system is DMARC (Domain-Based Message Authentication Reporting and Conformance). This method is used to identify and combat junk email. Instance: a fake sender address from a known and therefore trustworthy company.

Avoid "dead links" in your emails

Before sending an electronic mail, make certain that your emails do non contain any questionable redirects out of the e-mail or fifty-fifty expressionless links.

Email allows the subscriber to be removed from the recipient list.

Another valuable tip is the inclusion of a unique unsubscribe office that allows the recipient to be removed from the recipient listing. This is mandatory for marketing emails such as invitations and is automatically included in the Sweap electronic mail templates.

Use the office offered in Sweap to test your e-mails internally earlier they are really sent.

You can send test east-mails to various e-mail clients and so that you can follow the presentation of your e-mails internally before sending them externally on the "big journeying".

Apply DNS to verify your trusted identity.

This is a service that translates your domain proper name into an IP address or vice versa. By correctly setting up a forrard and contrary DNS lookup, your emails can exist ameliorate mapped and identified by the recipient. Forward DNS lookup is a verification of an IP accost associated with a domain name, whereas reverse DNS lookup is a verification of the domain name associated with an IP address.

Important information near reputation (the sender's IP address and domain)

The better the reputation of your IP address and your domain as a sender, the higher the probability of successful delivery of your e-mails.

Please recollect that "adept things accept fourth dimension". In order to build a positive reputation, you lot need fourth dimension, considering a positive balance has to be earned. Appropriately, both your sender IP and your domain should already have existed for a while and so that yous tin build up a positive reputation during this time.

In one case you take prepare a new domain, information technology is appropriate to utilise it slowly, "warm it up" and slowly only continuously increase the sending rate from it.

Caution: The deliverability is straight related to the reputation. The more than positive the reputation, the higher the delivery charge per unit of your e-mails. But this also works the other way circular: considering undeliverable eastward-mails have a negative impact on your reputation. That'southward why you should always take intendance to successfully deliver your e-mails to the recipients in terms of reputation.

Tips for a positive reputation:

Contact list maintenance

maintained, updated and personally fed contact list (contacts should e'er exist kept up to date and actually interested in receiving e-mails from you)
Subscription procedure for your contact listing should exist an opt-in or double opt-in (if yous want to subscribe to your emails, a confirmation will be sent first, which must be confirmed by the recipient before they are added to your contact list) Since the new DSGVO came into force, the use of the double opt-in registration procedure is all the more recommended.
continuous maintenance of your recipients (remove inactive addresses, remove people who do not open letters from the contact listing, as well as remove all addresses returned with blockings, unsubscriptions, spam complaints or errors)
Keep lists as clean every bit possible (not only improves e-mail statistics, merely also increases the chances of reaching the inbox)
Disposal of a public WHOIS*, as this indicates that a legitimate person is backside it
Segmentation of your e-mail contact lists (special target groups are noted with special needs, so that no mass e-mails are sent, but several eastward-mails adapted to the target group)

*WHOIS are the identity card of your website, they tell what is backside the domain name (i.e. the administrative and technical director of the domain). WHOIS list contact data of each entry. Since hiding the WHOIS is preferably done past spammers, a public WHOIS helps y'all considerably in your positive reputation.
