After obtaining an API key from SendGrid, you can either
CL-USER> sendgrid:*api-key-environment-variable-name*
"SENDGRID_API_KEY" ; default environment variable name, you can change it.Then you can do it by OS built-in facility, such as
export SENDGRID_API_KEY=your_sendgrid_api_key_valueOr set it using UIOP

Without a from name, your sending email will be the name of the email. Use the optional :from-name key to add a more appropriate sender name.
(sendgrid:send-email :to "[email protected]"
:from "[email protected]"
:from-name "Jane Doe"
:subject "Sending emails from SendGrid is fun!"
:content-type "text/html"
:content "<h1>A title</h1><br/><strong>Sending emails from SendGrid is fun!</strong>")The :send-at key takes a unix epoch time and sends your email at that specific time.
Free sendgrid accounts (at this time - 4th Oct 23) are limited to sending up to 3 days in the future. Therefore the :send-at key is limited to sending emails between 1-3 days in the future.
To send an email now, you can omit the :send-at key (see examples above).
Use the function (now-plus-n-days n) where n can be 1, 2, or 3 days in the future. This function will return the epoch time for that future date.
(sendgrid:send-email :to "[email protected]"
:from "[email protected]"
:from-name "Jane Doe"
;; send email 2 days in the future
:send-at (now-plus-n-days 2)
:subject "Sending emails from SendGrid is fun!"
:content-type "text/html"
:content "<h1>A title</h1><br/><strong>Sending emails from SendGrid is fun!</strong>")You can use the :attachments key to send attachments. Set attachments to t and then you can use the :file and :filename keys to provide your attachement.
:file takes the path to the txt file you want to attach.
:filename takes a string that represents the file name of the attachment.
Example:
(sendgrid:send-email :to "[email protected]"
:from "[email protected]"
:from-name "Jane Doe"
:send-at (now-plus-n-days 2)
:subject "Sending emails from SendGrid is fun!"
:content-type "text/html"
:content "<h1>A title</h1><br/><strong>Sending emails from SendGrid is fun!</strong>"
:attachments t
:file "/path/to/txt/file"
:filename "filename.txt")Ensure that the :file is a path to your pdf file and the :filename ends with .pdf.
Example:
(sendgrid:send-email :to "[email protected]"
:from "[email protected]"
:from-name "Jane Doe"
:send-at (now-plus-n-days 2)
:subject "Sending emails from SendGrid is fun!"
:content-type "text/html" ;; this is the content type of the email, not the attachments.
:content "<h1>A title</h1><br/><strong>Sending emails from SendGrid is fun!</strong>"
:attachments t
:file "/path/to/txt/pdf/file"
:filename "filename.pdf")You will receive an email with the attachment filename.pdf. The content of the file will match that of /path/to/pdf/file.
Inside sendgrid, if you navigate to Marketing --> Contacts, you can create a contact list. A contact list is a specific segment of people that did, or will do a specific action. For example, you can have a contact list for new subscribers to your product.
A list can have automatic actions attached to it. For example, you can trigger an email automation based on somebody subscribing to the list (This is managed in Marketing --> Automations).
With the add-contact-to-list function, you can add a single contact to a specifc contact list by using the list-id.
Note - you can find the list-id at the end of the contact list url. For example https://mc.sendgrid.com/contacts/lists/ac32607e-e253-490b-a171-d84d88xxxxxx, in this case ac32607e-e253-490b-a171-d84d88xxxxxx is the list id.
