Using SendGrid SMTP Integration for bulk email

Question

Is there a way to use SendGrid's SMTP Integration API for sending bulk mail?

Here's what I have in mind: I need to send a large bulk of emails to subscribers. Since SendGrid docs recommend using SMTP Integration where possible, I would like to be able to make a single hit SendGrid and let it send the whole bulk based on email list. I know this is possible with REST API.

Is this even possible with SMTP?

Yes, this is possible with the SMTP api as well. You can check out the SMTP developers guide to see how to design this, https://sendgrid.com/docs/API_Reference/SMTP_API/integrating_with_the_smtp_api.html .

You can also check out another Sendgrid user's implementation to send bulk mail with the SMTP api here, http://community.sendgrid.com/sendgrid/topics/_net_c_cshap_api?from_gsfn=true

I've seen the documentation before, but the only thing resembling what I need is adding multiple addresses to "To" field. Does this mean that each of the recipients will have the complete list of destination email address? – mkvcvc Mar 13 '13 at 19:26

When you use the TO array in the X-SMTPAPI header, SendGrid sends a unique email to each user, so the complete list will not be visible. – bwest Mar 13 '13 at 21:22
