Step 1 - Login to your Let’s Calendar account and navigate to Settings -> Email Config


Step 2 - Select “SendinBlue (Brevo)” under Mailing service and set it up with following details -



Step 3 - Title – Give a friendly title typically your domain / sending name related so you can identify easily e.g. Info @ Let’s Calendar (Brevo)


Step 4 - Now rest settings we need to enter as per what we copied from Brevo under Your SMTP Settings and is in your notepad


a. SMTP – this should be pre-filled as smtp-relay.brevo.com, please confirm this is same as what you see under SMTP server, if not enter the same

b. Port – 587 (OR as displayed to you by Brevo)

c. Encryption Type – TSL

d. Access key / Username – Enter what was displayed against Login under SMTP Settings 

e. Secret Key / Password – This should be same as the password you generated in Brevo SMTP API settings and have copied safely.


Step 5 - Now we have to add at least 1 verified email id to complete the setup (You can add more later)




Enter the “Senders Name”, this should be same as what you want your users to see when they receive calendar invite's from you.


Next, Enter Sender Email ID and Reply-to Email id – enter same as that you entered in Brevo.


Click “Submit” and you should get a confirmation message! 


Congratulations! You have successfully configured your SMTP settings with Brevo, next would be to test out the configuration by sending a test calendar invite.
