Verified Senders: Sender Domain vs Single Sender Emails
To be allowed to send through your account you must send from a verified sender. We offer two options to achieve this which include verifying your Sending domain or a Single sender email address on the 'Sending > Verified Senders' page of your dashboard.
Below covers the differences between the options to help ensure you pick the best option to suit your needs.
Sender Domain - highly recommended, generally required
Verifying the sender domain ensures you get optimal delivery rates as your domain will align for SPF and DKIM. Without this, you may encounter emails going to junk/spam folders, bounces or emails being quarantined due to recipient servers checking for SPF and DKIM alignment. As filtering becomes more strict to protect against spoofing/phishing, this is the best option so your emails have the highest chance of landing in the recipient's inbox.
Verifying the domain also provides the advantage of being able to send from any valid email address at the domain.
This option involves adding the domain to the 'Sending > Verified Senders > Sender domains' section where you're provided with three CNAME records to add to the domain's DNS settings. The three records take care of SPF, DKIM and tracking (open & clicks). Further detail can be found on the Verified Senders page. Note: you do not need to update your domain's SPF record directly.
If you are unsure in regards to adding the records, we have setup guides for common providers or we recommend speaking to your DNS provider's support team and asking them to make the additions for you.
If the CNAME records have been added but the domain is not showing as verified on the Verified Sender section in your account it may either need more time for the updates to propagate or contact our support team to investigate and ensure the records have been added correctly.
Single Sender Email
We only recommend this option if you do not have the ability to verify the domain of the email address you are needing to send from.
Verifying a Single sender email allows for a quick setup but the main disadvantage is that the domain will not align with SPF and DKIM. In some cases, without this alignment, this can result in emails being bounced or quarantined or sent silently to spam folders.
This option involves adding an email address to the 'Sending > Verified Senders > Single sender emails' section and we then send an email to the email address which includes a verification link. Once clicked, the email address will be verified and have the ability to send via the account.
Note: The free plan allows a maximum of 5 verified senders (domains and single sender emails combined) vs paid plans which do not have a limit.
