Frequently Asked Questions

Outgoing SMTP service

• What can I use mySMTP for?

  If you use mySMTP as your outgoing e-mail server, we ensure that you can send your e-mails from networks that are normally not open for you to send your personal e-mails from your PC or mobile device. It is typically the case that Internet providers are very restrictive when it comes to providing access to outgoing SMTP servers by, among other things, blocking port 25, which is a standard outgoing port. mySMTP uses port 25 and 2525 if open and 587, which is always open. All devices and systems that can send e-mail can use mySMTP

• What does SMTP mean?

  SMTP is the abbreviation of Simple Mail Transfer Protocol. In other words, SMTP is the standard system that is used when your e-mail is to be sent out into the world. There is a more detailed description of the SMTP protocol in Wikipedia.

• Why can’t I just use my Internet provider’s SMTP server?

  The outgoing port 25 is typically blocked in other networks when you try to send e-mail. mySMTP uses port 587 and 2525, which is always open. In this way, mySMTP is an open alternative that gives you the freedom to e-mail in all networks. If you are to send a lot of daily e-mails, you will also often find that your provider restricts amount of e-mails that are sent daily.

• Why not use a browser webmail such as Gmail and others?

  With mySMTP you do not have to log in and send using different e-mail addresses and thus compromise your professional identity. mySMTP makes it possible for you to send your personal e-mail using your own domain regardless of where you are.

Subscriptions & Prices

• What is mySMTP.com Lifetime Free?

  After sending e-mails to all of Denmark and the rest of the world since 2007, we know that many people only need to send maybe 10-15 e-mails a day. That's why we now offer a totally free lifetime subscription to you or your company that covers these daily volumes.

  With Lifetime Free, you receive up to 15 e-mails daily (24 hours interval).

  Cc and Bcc are take into consideration towards the counting of the 15 daily e-mails.
  You send with your own identity and there will be no advertising in your e-mails sent via mySMTP.com

• How do I start using my mySMTP account?

  If you have tested mySMTP free of charge and want to continue with a paid subscription, all you have to do is log into your account from the www.mysmtp.com home page.
  Your information is already in the system, so all you have to do is choose which subscription you would like to continue with. Then you receive a receipt for your purchase.
  If you buy a subscription without testing first, you just have to choose a subscription in the subscription overview. Your account will be active as soon as payment has been processed. We accept all major credits cards and PayPal.

• Which subscription should I choose?

  1. If you are a single user (one e-mail address) with normal e-mail requirements, a Basic subscription would suit your needs. This subscription lets you send up to 100 e-mails a day.
  2. If you want to share your mySMTP subscription with family or friends (up to three e-mail addresses), you should choose Family.
  3. If you need SMTP service for more people, for example a company or a work group, you can choose between different Premium subscriptions. The Corporate subscription gives you up to 3000 daily e-mails.
  4. The Small Business subscription gives you the possibility to send up to 300 e-mails a day with five different e-mail accounts. Read more detailed descriptions of the subscriptions here.
  5. Time-limited subscriptions can be for one to three years. There is a discount for two and three-year subscriptions. (Two years: -15% and three years: -25%)
  6. You can also buy optional Buffer E-mails for your subscriptions so that you have extra e-mails if your daily maximum has been used.
  7. Emails To Go is a subscription type that can be used if, for example, you only need to send e-mails to a distribution list occasionally. Here you can choose the volume of e-mail credits that suits your e-mail needs.

• Can I use the same mySMTP subscription for more e-mail software and mobile devices?

  You can share your SMTP login with an unlimited number of users. If you would like to have separate statistics for the users, they must have their own logins for a multi-user account and you should also be aware of whether the daily e-mail volume is enough for a number of users. For optimal security, we recommend using separate logins.

• How many e-mails can I send at one time if I have a subscription for 100 e-mails a day?

  With this subscription, you can send e-mails to, for example, 10 ordinary recipients and 90 Cc or Bcc recipients. Each recipient counts as one e-mail transmission, including Cc.: and Bcc.: If you have an account with a number of e-mail accounts, for example Family, the daily volume of e-mails that is available is shared. If you sometimes need more e-mails than the daily maximum, we can recommend buying Buffer e-mails.

• Can I e-mail using mySMTP abroad?

  Yes, with mySMTP you do not need to change your e-mail set-up just because you are travelling. If you have set up your machine to use your mySMTP login and password, you are able to send e-mail from all foreign networks. If the foreign network provider or network administrator blocks port 25, which they often do, you can simply change to port 587 or 2525.
  So now there is always access from airports, hotels and the inland Greenlandic ice sheet.  

• How can I extend and upgrade mySMTP subscription?

  You can extend your subscription online by logging into the dashboard at mySMTP. Ten days before your subscription expires, you will receive an e-mail from mySMTP, reminding you that it is about to expire. If you subsequently do not do anything, a final reminder will be sent by e-mail two days before your subscription expires and on the final day itself. After your subscription has expired, you can always reactivate it.
  If you want to upgrade, for example from a Basic subscription to a Small Business subscription, this can be done using your account administration.

• Is it possible to purchase more daily e-mails?

  Yes, you simply log into your account from the home page and then purchase Buffer e-mails. For example, if you send more than the daily maximum, Buffer e-mails will be sent automatically so that everything reaches its destination.

• How can I pay?

  mySMTP accepts payment by VISA, VISA Electron, JB, MasterCard, PayPal and Bitcoin (only for dedicatd servers) mySMTP use 3-D secure for extra security.

• What can I see in my account dashboard?

  The dashboard provides you with information and detailed sending statistics for all e-mails with a time stamp. You can also administer SMTP logins, see payment history and much more.

• How quickly can I get started?

  The account will be active as soon as you have paid. You will receive an invoice for payments that have been made and a set-up e-mail.

• What are E-mails To Go?

  If, for example, you only need to send e-mails a couple of times a month to a mailing list, E-mails To Go may be the solution. Here you buy a fixed volume of e-mails, which are available until they are sent without any time-limiting subscription with daily e-mails. E-mails are available as long as you are registered as an mySMTP customer.

• What are Buffer e-mails?

  Buffer e-mails give you extra e-mails that can be used if you exceed your daily limit of, for example, 100 daily e-mails. Then e-mail 101+ will be sent via your Buffer e-mail account. Up to 100,000 buffer e-mails can be purchased.
  Buffer e-mails are available as long the account is active.

• Can I use a free e-mail address like gmail, hotmail etc for sending e-mails?

  Free e-mail addresses like gmail, hotmail, outlook etc unfortunately cannot be used to send with. Because of the risk of abuse, Google and Microsoft have shut down the possibility to use their e-mail addresses for use in other servers than their own.

Technology & Security

• Can third parties read my e-mail when I send them from mySMTP?

  No, mySMTP has a high level of security and regularly updates its security systems. In addition, our servers are only for outgoing e-mail transmissions. Sent e-mails and content are not stored in the SMTP server either. Only if the e-mail for one reason or another cannot be delivered to the recipient, attempts will be made to send the e-mail for 48 hours from when it is received by SMTP, after which time the e-mail will be deleted from the system’s queue and a non delivery bounce message will be sent from the failing receiver.

• How can I see whether my e-mail has been sent and received?

  On the dashboard, you can see all of the details about any sent e-mail and received e-mail in the detailed transmission statistics and log.

• What is the largest attachment that can be sent?

  With mySMTP you can send e-mails up to 25 MB in size. Many mail servers are configured to receive e-mails that have a maximum size of 25 MB, but this is far from always the case. If, for example, you have 20 recipients of a large e-mail to the same receiving server, it can cause big problems in the network that is to receive the e-mail. Therefore, it is recommended that you do not always send large e-mails. An e-mail with an attachment that is 20 MB large will be transformed into 25 MB when it is sent as an e-mail. You might compress files before you send them. Alternatively, use an FTP or Dropbox.

• My e-mail was sent, but the recipient did not receive it – why?

  There can be many reasons why an e-mail does not arrive. It is a good idea to find out whether it has gone into the recipient’s spam folder. There might also be technical problems at the receiving end. If an e-mail cannot be delivered, you will normally always get a bounce message that explains the reason. In order to achieve optimal delivery, we recommend that you use SPF, DKIM and DMARC records, which are explained below.

• How do I set up SPF, DKIM and DMARC in my sender domain?

  Together with our set-up e-mail, you will receive an SPF record, which covers all of our servers’ IPs and domains. The SPF record that is placed in the sending domain’s DNS record verifies the sending network and receiver that this domain uses mySMTP.com as the outgoing server. The SPF record for use together with mysmtp.com is: v=spf1 mx a include:web.shared.mysmtp.com ~all.
  In an existing SPF record for your sending domain you should add this  : include:web.shared.mysmtp.com
  DKIM is a unique key that is included in all of your e-mail headers, which verifies that you domain is valid for sending via the SMTP server.
  DMARC is primarily an anti-phishing certification, which ensures that your domain cannot be used for malevolent phishing and other similar domain spoofing. You can set up your own DMARC record by using this wizard. DKIM can be ordered directly via Denne e-mail adresse bliver beskyttet mod spambots. Du skal have JavaScript aktiveret for at vise den.. We provide advice about this, if necessary.

• Does mySMTP use outgoing TLS encryption?

  Yes, mySMTP supports TLS 1.1 and 1.2. We do not support SSL

• Why should I use outgoing port 587?

  Port 587 is the alternative e-mail port that is always open in the network. So if port 25 is closed in a foreign network, you should use port 587 or 2525.

• Where is the mySMTP hosting centre?

  Our data centre is in Copenhagen.

• How do I set up my e-mail software for mySMTP outgoing e-mail?

  All devices that can send e-mail can use mySMTP.com. You can find manuals for most e-mail software in our Guides section.

• My scanner/printer cannot use the SMTP login – can this be fixed?

  Yes, if you get the IP number behind the device, we can whitelist the IP number and the device can then send. You just have to send the IP number and we will take care of the rest.

• My e-mail client ‘cannot connect with the SMTP server’.What should I do?

  Check the port number behind your e-mail client. You can connect with the SMTP server and ask for the available port number using the TELNET protocol: Click Start, select Run… Then enter cmd in the box and click OK. Then an MS-DOS prompt will open. Enter the following: telnet smtp.dk 587. Click OK to connect with the SMTP server. If the connection is OK, a reply will come from the mail server in the Telnet window: 220 smtp.dk ESMTP Postfix (Debian-GNU). If you have not been able to connect through port 587, you can try using port 25 and 2525. If these do not work, there may be a blockage in the firewall, which your administrator must open. Alternatively, you can also use IP number: 

  185.51.78.140

• IP Whitelisting for devices that can't do SMTP authorization

  If your application can not use SMTP authorization with username and password (typically scanners and older-date printers, accounting programs and sensors), we can whitelist the IP address the device uses in your network. For example, to find your IP number, use a service like whatismyipaddress.com. The following setup should then be used: For whitelisting setup, outgoing SMTP is used: whitelist.mysmtp.com or IP 93.90.117.28 The device that sends must have a FROM e-mail that is active on your SMTP account - that's the way we can verify that account May use whitelisting. For example, if you have a user named Denne e-mail adresse bliver beskyttet mod spambots. Du skal have JavaScript aktiveret for at vise den., it must also be a sender on the device.

• What support does mySMTP offer?

  You can reach us by e-mail at Denne e-mail adresse bliver beskyttet mod spambots. Du skal have JavaScript aktiveret for at vise den. and Skype: smtpsupport  

• Where can I see the status of the service?

  This status page will always be updated with service messages: mysmtp.statuspage.io

mySMTP Dedicated Cloud Server

• What is a dedicated SMTP server?

  A dedicated SMTP server sends using its own IP number, which you have sole responsibility for regarding sending reputation. It also has its own resources based on cloud technology, so, for example, more disk space and RAM can be added on short notice as needed. This type of server will also send significantly faster than a shared SMTP server - up to 25 e-mails per second. We recommend this product to the business that is to send large volumes of e-mail to lists or that need an SMTP server for more operationally critical e-mail transmissions, such as transaction e-mail, receipts from e-commerce, e-mail receipts that confirm dates etc.
  Both shared and dedicated SMTP servers send in accordance with the e-mail certifications SPF, DKIM and DMARC, which ensure the best possible receipt.

• Can I send a million e-mails a month?

  Yes, if your e-mail list consists of subscribers who have agreed to receive your e-mails. We do not allow third-party e-mail lists without OPT-IN.

• Do you have a SPAM policy?

  Yes, of course we do not tolerate spam of any kind. Read our policy here

• What does ‘sending reputation’ mean?

  The IP that you send from combined with the domain creates a reputation for sending in the network, based on many different parameters. If, for example, there are many people who mark your e-mails as being spam, your sending reputation will quickly become poor. Blacklists keep track of whether all rules are complied with and whether your domain, for example, is SPF, DKIM and DMARC certified. mySMTP also monitors all sending IPs and can help with the problems that sometimes arise. It is most important that the rules regarding OPT-in and third-party data are complied with.
