The default one-click welcome automation is one email that sends immediately after signup, and includes pre-filled content. In the automation builder you can change the delay, and edit the design and content. This automation welcomes new subscribers to your audience, so the trigger and audience are fixed and uneditable. You can pause the automated welcome email at any time. If you need more sending options, check out our advanced workflow.
When it comes to deciding how to craft that perfect subject line, there appears to be really only one area to avoid: the subject line of 60 to 70 characters. Marketers refer to this as the “dead zone” of subject length. According to research by Adestra, which tracked over 900 million emails for its report, there is no increase in either open rate or clickthroughs at this 60-to-70 character length of subject line.
