Rob, you don’t say who ‘booted’ you from using it. A significant GDPR factor is non-profits having to consent/re-consent those on established email lists and experiencing significant proportions of lists being lost because people miss the notifications or are too busy to fill in yet more forms. However, I have found a few using a ‘one-touch’ re-subscription button that takes immediate effect, without the recipient having to do anything else. It would appear that the re-subscription rate is higher, the easier it is to activate. On enquiry, I was told that they were using mail chimp for this.
A 2011 meta analyses has found that the factors with the greatest impact on sales performance are a salesperson's sales related knowledge (knowledge of market segments, sales presentation skills, conflict resolution, and products), degree of adaptiveness (changing behaviour based on the aforementioned knowledge), role clarity (salesperson's role is to expressly to sell), cognitive aptitude (intelligence) and work engagement (motivation and interest in a sales role).
A lead magnet (a.k.a. an optin bribe) is something amazing that you give away for free in exchange for an email address. This doesn’t have to cost you anything to create; most lead magnets are digital materials like PDFs, MP3 audio files, or videos that you can create yourself at minimal or no cost. It can be absolutely anything you want, so long as it provides value to your visitors for free.
In addition to satisfying legal requirements, email service providers (ESPs) began to help customers establish and manage their own email marketing campaigns. The service providers supply email templates and general best practices, as well as methods for handling subscriptions and cancellations automatically. Some ESPs will provide insight and assistance with deliverability issues for major email providers. They also provide statistics pertaining to the number of messages received and opened, and whether the recipients clicked on any links within the messages.
