Sender addresses

What is a sender address?

The sender address is the address displayed in the "From" field when receiving an email.

What addresses can I use as a sender address?

The default sender address will automatically be the address you used to open your free account. If you'd rather use a different address, you can change it for another valid email address by following these instructions.

It's also possible to have several sender addresses in an account as there is no limits on the number you can add. One of your employees could, for example, want to send a more personalized email to his client list. This employee could then use his/her email address as a sender address. For mailings relevant to the entirety of your client list, you could instead use a more general address such as info@yourdomainname.com... You'll however have to determine one default address that will be used for all automated processes in your account such as opt-in emails, unsubscription confirmations or consent confirmation emails.

You can use whichever email address you want to as long as it's a valid address that belongs to you or the person it belongs to authorizes and validates the email address. Keep in mind, however, that despite being able to use them, some email addresses are not recommended. Click here for more details about this situation.

Before using a sender address, you'll need to validate it. In order to validate the email address, an email will be automatically sent to the specified address with a validation link. Only after the validation link will have been clicked will the address be useable as a sender address in your account. If you wish to add an address that doesn't belong to you, don't forget to let the owner of the address know to make sure that he/she completes the validation process.

Choosing your sender address:
  • We recommend you always use an email address with a domain name linked to your business (ex: info@yourwebsite.com). This will give your emails a more professionnal look and will put the recipients of your emails more at ease. However, if you have a DMARC policy on your domain name, some adjustments may be necessary before using it as a sender address. Click here to find out why.
     
  • Adjusting the first part of the address to reflect the purpose of your email may help your recipient filter your mailings better. You could use something like newsletter@...for information bulletins, promo@... for upcoming promotions etc.
     
  • Try to avoid email addresses from free mailers (Gmail, Hotmail etc). These types of addresses are often used by spammers and could potentially hurt your chances to deliver your email to the inbox. Furthermore, you have no control over the domain name, which means you're at the mercy of any changes to their policies.
     
  • We strongly advise against using addresses from Yahoo and AOL. Here's why.
     
  • Don't use disposable or temporary email addresses (these addresses have limited usage).
     
  • Avoid the use of "noreply@" email addresses. Those addresses have a tendency not to perform well with antispam filter, on top of being perceived badly by the email recipient. You may be tempted to put a noreply address because you don't want to filter autoreplies and absence notices. However, great exchanges and relevant questions can be hidden between those autoreplies. Take the time to answer your recipients' questions. Great customer service is an important part of a business reputation. Moreover, people replying to the email you sent create positive engagement, which will help your sender reputation. Not being able to reply to an email received can create frustrations, a higher unsubscription rate and more abuses reported.

Why is my sender address not recommended?

If you see this kind of message, it means the address you want to use is using a DMARC policy on its domain name. A DMARC policy protects a domain name from identity theft. It works hand in hand with the SPF and DKIM authentification methods.

Getting  a DMARC policy on your domain name is an excellent business practice. Then why do we say the address is not recommended? When an email is sent, the server that receives the email will verify if a DMARC policy exists on the domain name (from). The DMARC policy lets other servers know about your authentication practices and contains instructions for the servers about how to treat your email if verification processes fail: do nothing, quarantine your emails or reject them. If your policy is set to "do nothing", your email will go through even if the authentification process fails and the consequences on your delivery rates will be minimal, if there is any. However, if the policy is to quarantine or reject your emails, your delivery rate will be negatively affected and might mean your emails will simply never reach their destination. Keep in mind that it doesn't prevent you from using your sender address as is, but you might be a little disappointed in your results and statistics.

Your domain name has a DMARC policy?

 Contact us so that we can give you the instructions to ensure the best delivery of your emails.

It's possible to make changes that allow emails sent from our platform to respect your DMARC policy and prevent delivery problems. These changes are, however, only possible if you manage the DNS of your domain name. You won't be able to apply these changes to a Yahoo or AOL email address since you don't have control over their DNS. It would then be preferable to use another email address as your sender address. If you're using your own domain name, you'll be able to apply the necessary changes. You'll, however, need to possess the necessary knowledge on DNS or to ask your domain name host.

You have a DMARC policy on your domain name but don't have any warning in your account on your sender address?
This probably means that the action defined in your policy for how to handle emails that come from your domain and fail the DMARC check is "to do nothing with them. The impacts will therefore be more minor than if the action was explicitly to quarantine or reject them. If the warning message is not visible, it may also mean that changes have already been made with us to allow you to use our services while respecting your DMARC policy.  If you're not sure and need more details, don't hesitate to contact us.

How to add sender addresses

Here's how to proceed to add a new sender address for your mailings:

  1. Click the gear icon at the top right of your screen and select Sender addresses.


     
  2. Click on "Add" to enter a new sender address:


     
  3. Enter the address in the email field and click "OK".


     
    Reminders:
    - It's not recommended to use a Yahoo or AOL sender address. We don't recommend email addresses from free mailers such as Gmail or Hotmail either. Learn more.
    - If you get a warning that your sender address is not recommended, there probably is a DMARC policy in place on the domain name for the sender address you wish to use. Learn more.
    - Don't use a disposable or temporary email address because these addresses have limited usage.
     
  4. A validation email will be sent to the address. You will need to click the validation button contained in the email in order to confirm you have ownership of this address. You can then use this address for your mailings. All validated email addresses will show "Yes" in the validation column. If the address still doesn't show that it's been validated, make sure to refresh your webpage.


     
    Email addresses that haven't been validated can't be used. If you haven't received the validation email, click on "Send a validation" to send it again.

Frequently asked question

Could someone use my email address without my consent?

No. It's not possible to use an email address if the owner of the address didn't validate and authorize it firsthand. As soon as an address is added to an account, a validation email is sent. The owner of the email address will have to click the button in the email in order for the sender address to be useable in the account. As long as the address is not validated, it can't be used.

How can I authenticate my emails? Should I make any changes to the Sender Policy Framework (SPF) of my domain name?

To ensure best possible delivery of your emails, we already authenticate your emails with our SPF and DKIM. It's therefore not mandatory to make any changes on your end. Including our servers in your SPF entry could, however, improve deliverability of your emails. Contact us to get the necessary information.

Why is there a "on behalf of" mention in Outlook and "Via" in Gmail?

As mentioned above, all emails sent through our service benefit from our authentication and therefore, the excellent reputation of our email servers. When you send a bulk email, there are two email addresses used for sending: the address in the "From" field and the sending address (known as Mail From or Return-path). The first address is visible to the recipient. This is the email address you have chosen in the configuration of your mailing. The second address, which is the real address of the mailing, is usually hidden in the header of the email. This is an address with our domain name. It's necessary to use this address to send your messages to ensure the authentication of our email servers and also to receive and process bounces. Because your email is authenticated with our domain and is different from the address in the "From" field, some email software such as Outlook and Gmail display this information to indicate to the recipient that we are delivering on your behalf. This mention is mostly specific to these two email clients and shouldn't have any impact on your deliverability rate. Also, it's not possible to remove our authentication, because the email is sent from our servers. On the other hand, you can contact us to ask us to add a DKIM signature with your domain name to your mailings. This will remove the "via" mention in Gmail. However, this unfortunately has no effect in Outlook. In most other email software, only your sender address will be visible in the "From" field. Contact us for more information
 

Why free email services addresses are not recommended to use as sender addresses?

Free email services such as Yahoo!,  AOL, Hotmail, Outlook, Live and MSN use various mechanisms to verify the origin of emails. This validation is performed on the sending address (FROM) of the email, as well as on the origin of the email (the IP address of the server sending the email).  This is intended to significantly reduce fraudulent emails, as Yahoo!, AOL, Hotmail and others are constantly being used to commit fraud. For example, in the case of Yahoo! and AOL, they use the DMARC policy which has the effect of classifying emails with a sending address (FROM) ending in @yahoo... as fraudulent if they are not sent from their servers.  The result is that emails aren't delivered to the final recipient. For this reason, we strongly suggest that you don't use a Yahoo! or AOL address or other free email services.

We encourage you to use an email from your company as your sender address, for example info@yourcompany.com. This way, your e-mails will get to their destination and look more professional than if you use a free e-mail service. In addition, you will no longer be at the mercy of these services, which can change their policies at any time and thus affect your delivery rate.
 

Can I use a  "noreply@..." sender address?

Yes, it's technically possible to use a "noreply@..." address, as long as you can validate the sender address when you add it to your account. However, we strongly advise against it. Those addresses have a tendency not to perform well with antispam filter, on top of being perceived badly by the email recipient. You may be tempted to put a noreply address because you don't want to filter autoreplies and absence notices. However, great exchanges and relevant questions can be hidden between those autoreplies. Take the time to answer your recipients' questions. Great customer service is an important part of a business reputation. Moreover, people replying to the email you sent create positive engagement, which will help your sender reputation. Not being able to reply to an email received can create frustrations, a higher unsubscription rate and more abuses reported.
