What Is Email Warm-up
Email warm-up is the process of gradually building the sending reputation of a new email account or domain before sending large campaign volumes. Over a period of weeks, you send a small number of emails each day, then slowly increase. The emails go to real recipients (or warm-up networks) who open and reply, signaling positive engagement. This builds trust with email providers (Gmail, Outlook, etc.) so they treat your domain as a legitimate sender.
How to Activate Email Warm-up in Enginy
Email warm-up in Enginy has a fixed cost/month (ask either your account manager or the chat support) and must be activated by your assigned Account Manager. You can warm up one email address at a time by a single warm-up seat.
Go to the Identities section.
Select an identity, then navigate to Configuration > Email > Manage tab > Start button
After two weeks, go back to Identity Configuration > Email > Manage tab and stop the warm-up. You can now send email campaigns from that address.
Warning:
Do not send email campaigns from the address while it is warming up.
You will receive automated warming emails during this period. Do not mark them as spam — this would defeat the purpose. Simply open and archive them.
Important: Even after the warm-up period, continue monitoring email performance. If you plan to further increase volume, do it in small steps. For scaling to very high volumes, add more domains or addresses and warm them up too, rather than pushing one domain to its limit.
What Happens if You Skip Warm-up
Emails flagged as suspicious — Email providers notice sudden high-volume sending from a new source. Emails are likely routed to spam.
Sending limits or blocks — Providers may block or suspend your account for what looks like spam activity.
Poor deliverability — Your first campaign will likely have a very low inbox placement rate, and recipients may mark unfamiliar emails as spam, further damaging your reputation.
