Q: Why I can not receive warmup emails, but can send?
A: When you can send warmup emails but not receive warmup emails, it means that we can not verify deliverability to that account. We use a total of 3 third-party email verification services to check deliverability for newly connected warmup accounts (Zerobounce, Emailable, and MillionVerifier) - if none of the three are able to verify deliverability, that's when we pause sending to the account (to prevent bounces for other accounts in the pool).
Kindly reach out to our support and list the email accounts that are having this issue.
Q: Why is my warmup not reaching the sending limit?
A: The daily warmup limit is an upper threshold - it's not a hard limit that the algorithm tries to hit; in other words, the ultimate goal is to improve deliverability and not to hit a specific email limit every day.
An earlier version of our warmup algorithm would actually work in that way - i.e., it'd hit the user-defined limit every day. We found out over time that it wasn't really the best/fastest way to warm up accounts. In a lot of cases, it could actually damage your sender's reputation.
This is why the dynamic randomizer was added - the algorithm automatically determines the correct number of emails to send based on your existing health score and several other factors.
Q: What will happen with warmup stats if we reconnect the email and what will happen if we re-add the same email address?
A: If you reconnect or re-add the same email address, data will not be lost. Both warmup and account stats show up.
Q: Why are my warmups being received in huge numbers?
A: This happens if the warmup pool suspects a potential issue with the account (specifically a potential warmup detection by the ESP) and needs to increase the ratio of emails received.
There is nothing wrong with this and it will mellow out over the next week or so.
Q: How to know if my accounts have been warmed up enough?
A: We usually recommend warming up new domains/accounts for at least 2-4 weeks and old accounts /domains for at least 21 days before starting your cold outreach campaigns.
To learn how long your accounts have been warming up, go to your email account inbox (Google, Outlook, etc.), open the warmup folder, or the sent folder, search by your warmup user tag, and see when the first email was sent/received.
Also, we recommend keeping the warmup activated indefinitely as long as you plan to use these accounts.
Q: If I change my sending account name is this going to affect the warmup?
A: If you only change the name but keep the same domain then it doesn’t reset the warmup period, but it's recommended to warm up the account for another 2 weeks if possible.
Q: Mid-February, Google banned auto-warmers. What action did you take to remedy this and continue your automated email-warming strategy?
A: Instantly is not using Google API for email warmup and isn't affected by the new Google changes. Everything will continue working as it has been.
It's still a smart move to diversify your email accounts. If you're using only Google emails, also get Outlook or other ESPs so you're protected against any bigger changes in the future.
Q: Why is warmup not sending and I have enabled it?
A: Warmup emails are scheduled at 12 am UTC every day since we need to run several tests before adding a new account to the warmup pool.
So if you enabled warmup for newly connected hours today, they will only start to send after the following 12 am UTC.
Q: How can we reset warmups?
A: If you're experiencing any issues or need to reset your warmup, you have 2 options:
You can choose to remove the email accounts for a period of 2 days based on UTC time, which will effectively reset the warmup.
You can also lower your sending limit for 2-3 days to achieve the same result.
