Before you set sail
A few things
you might wonder.
A good voyage starts with knowing what you're signing up for.
Is the email warmup really free forever?
That's the model: 10 warmup emails a day without a badge, or a higher free daily limit with a verified WarmupBay badge on your website. There's no trial period, no credit card requirement and no automatic move to a paid plan.
What does automatic warmup do?
Your mailbox exchanges warmup emails with other participating mailboxes. WarmupBay handles the sending and receiving, gradually building up activity within your daily limit.
Can I control the sending pace?
Yes. You choose a daily limit, build toward it gradually and can pause warmup whenever you need to.
What do the domain checks cover?
SPF, DKIM and DMARC are email records that help providers check who can send on your domain’s behalf. The checks highlight missing or incomplete setup so you can review it.
Does warmup guarantee inbox placement?
No service can guarantee that every email reaches the inbox. Warmup is one part of getting ready to send. Your domain setup, the relevance of your messages and who you send to still matter.
