Zoho Campaigns is an email marketing platform for creating, sending, and tracking your email campaigns. But before starting to send bulk emails you should authenticate your domain by setting up SPF and DKIM records.
For that, go to Domain Authentication from Settings, see the screenshot below,
Find the domain you want to authenticate and click on Setup,
See the screenshot below,
Once you click on the Setup button, a popup window will appear and you will see the SPF and DKIM records that Zoho Campaigns provides you. See the screenshot below,
Note: There is no need to set up SPF record for Zoho Campaigns, as the “Envelope From” domain will always be handled by the server of Zoho Campaigns.
For SPF to be aligned you should have your “From address” domain in the “Envelope From” address. Zoho Campaigns uses “zcsend.net” as the “Envelope From” domain, during the DMARC check, this “Envelope From” domain will not match with your “From address” domain, so SPF alignment will fail. This happens not only with Zoho Campaigns but with the majority of Email Service Providers. But during the configurations Zoho Campaign will suggest you adding this include include:zcsend.net in your SPF record. Just be informed that there is no need to do this, as SPF will fail due to misalignment, even if you add that include in your SPF record.
Zoho Campaigns has an article regarding the SPF alignment as well, you can check it out at this link, Why SPF alignment fails.
DMARC requires either DKIM or SPF to be authenticated and aligned, so you will pass the DMARC check even without SPF alignment. SPF alignment failing won’t affect your email deliverability if you have DKIM in place. Thus you need to set up only DKIM for Zoho Campaigns.
