We applied for the SendGrid accelerate program and got accepted!
We got credit worth $329.95/month (for 12 months). This will help us save a lot of cost for the next 1 year as we don't have to worry about paying for email servers.
In case you're wondering, startups participating in the SendGrid Accelerate program receive 12 months of product credit, access to mentoring, and networking opportunities exclusive to program participants.
They do not take equity of any kind. We highly recommend you apply for your startup. You can do that here: https://sendgrid.com/accelerate/
