And yet, very important! Once I used Sendgrid for bulk mail - most of the messages do not reach users, because sendgrid's ip-addresses are blacklisted.

So, if you have less than 40k subscribers, you can use sendgrid once for BulkMail. After that you better use other services or upgrade. 100 messages per day is too little, even for sending service notifications on a low-traffic forum.

In development mode newly created widgets for Custom Apps are working perfectly but in Production they disappear from Block Manager: Maybe somebody knows how to fix this problem?
