How we send email with human-like delivery.

Leadfwd Engage acts like a user of your email address. Engage sends emails directly from your mailbox as you would (human) instead of using a third-party sending service. This approach dramatically increases deliverability and also provides us the ability to identify replies to messages that we send.

Leadfwd Engage will send emails according to the rules set up by your email provider. You should know how many emails your provider allows you to send per day. You should also be aware of what content your email provider considers to be spam so that your outgoing messages do not trigger the safety mechanisms for outgoing emails.

AI-optimized Human-like Sending

Humans are rarely able to send an email more frequently than every 30-45 seconds. Sending multiple emails in a short time and divided by even time intervals might trigger SPAM filtering and prevention systems. Those filters are sensitive to such regularities. For that reason, we have designed Engage to imitate human behavior in terms of sending emails. By default, Engage will send your messages with random pauses in between each outbound send. We also never send messages concurrently from a single mailbox. Meaning a single outbound email send is completed, the routine is paused and then auto-resumes for another email to be sent. 

Our default sending limit is approximately 100/emails per hour and that's designed to optimize deliverability. If you need to increase your hourly output, you can and should add additional mailboxes to maintain your desired volume.

Sending multiple Sequences with the same mailbox

If several Sequences are set to go out from one mailbox simultaneously, the emails from all those Sequences will be sent from your mailbox in an interweaving way (1st email in one Sequence, 2nd in another). But the maximum daily send rate will be enforced along with our sending practices.

Reaching your daily limit

Every mailbox has a daily limit of outbound email sends using Engage. Your ISP may have lower daily limits as well, that you should check. Generally speaking our limits do not exceed most ISP's daily limits.

Daily limits:

Engage Essentials 600 emails per day / per mailbox

Engage Professional 1800 emails per day / per mailbox

When you reach your daily limit for a specific mailbox, recipients enter a pending queue and are given first priority for sending when the next sending window opens for a given Sequence. Once the queue is cleared, then follow up messages for other recipients resume.
