A new mailbox or sending domain has no reputation yet, so mailbox providers watch it closely. Raising volume slowly, to engaged recipients who asked to hear from you, gives them time to see good signals. This planner turns a start volume and a target into a day-by-day ramp.
Reaches 500/day on day 16, about 2,693 messages in total.
Send only to people who opted in, most engaged first. Hold the volume flat for a few days if bounces or spam complaints rise.
There is no fixed number. Many senders ramp over two to six weeks, and slower is safer when the domain is new or the list has not been mailed recently. Watch bounce and complaint rates and hold the volume flat whenever they rise.
No. Warmup only helps when the recipients asked for your mail. Sending more slowly to purchased or scraped addresses still produces bounces and spam complaints.
No. The planner runs entirely in your browser and keeps nothing after you close the tab.
Email warm-up is the practice of increasing sending volume from a new mailbox or domain gradually, so mailbox providers can build a picture of it before it sends larger volumes. Good warm-up relies on real, low-volume, wanted mail and steady growth, not on tricks. The extension's optional WarmTalk feature helps by running a paced conversation loop between two mailboxes you own.
7 min readSPF, DKIM and DMARC are DNS-based standards that let receiving mail servers check that email claiming to come from your domain is authorised. SPF lists which servers may send for you, DKIM adds a cryptographic signature, and DMARC tells receivers what to do when checks fail and where to send reports. Gmail and Yahoo now require authentication from senders, so this is a baseline, not an optional extra.
8 min readSince February 2024, Gmail and Yahoo have required senders to authenticate their mail, and bulk senders must also publish DMARC, support one-click unsubscribe and keep spam complaint rates low. Google describes bulk senders as those sending close to 5,000 or more messages a day to Gmail addresses. Google also advises keeping the reported spam rate below 0.1 percent and never reaching 0.3 percent.
