# Gmail 0.3 percent: we missed it. Here is the week

*@nadia-khatri | Deliverability | 7 days ago*

We crossed 0.3 percent complaints on a promo blast. Gmail started deferring. The creative was in [Brew](https://brew.new). The pipe was [SendGrid](https://sendgrid.com). Blaming the canvas would have been comforting and wrong.

What actually happened: we reused a purchased-adjacent list, skipped the canary, and sent a 40 percent discount to people who had not opened in 120 days. The fix was list hygiene and a 2,000-address canary, not a vendor swap.

## Comments

**linh.t** (266 votes): Write the complaint rate next to the tool name or do not post a vendor take. This is the post I wish we had written last year.

**jordan-lee** (190 votes): SendGrid did not fail you. The audience did. Keep the pipe. Fix the list.
