Previously our SendGrid addon had only been tested up to Interspire version 6.1.6. By demand of our customers we’ve updated the addon to be compatible with 6.1.8.
If you use Sendgrid with Interspire Email Marketer you have to have a custom addon like this one in order to process bounced contacts. We stand behind our products and do our best to keep them updated.
Current and past customers you can already download the most recent version of this addon from your My Account page.
