How deleting and adding lists frequently affects your email deliverability

Smart marketers keep track of their contact activity in every campaign report. This helps provide a clear picture of each contact's interests and helps you refine your future campaigns. If you frequently delete and add mailing lists, you will lose the consistency across reports, and this can lead to issues such as: 

Difficulty communicating with contacts

It will be more difficult to track your contacts' responses. Every campaign report provides a range of information on open rate, click rate, unsubscribes, spam complaints, and bounces. When you delete and add lists, you won't be able to track your contacts' responses across multiple emails. You may even lose track of which list was used in which campaign.

A campaign report using one list can't be compared directly with the report from a campaign using a different list or the same list with a different set of contacts.

Contact engagement is useful for optimizing email deliverability and you can only track your contacts reactions to help you refine future campaigns if you are using a consistent list.  

Contact engagement gap

  1. It is very easy to miss out some contacts during the deletion and addition process, which may mean you lose potential customers. 
  1. If you do find some of those missing contacts and send them emails after long engagement gap, they may not recognize your email and may mark you as spam.  

Duplicate campaigns

You risk sending the same email repeatedly to contacts if you frequently delete existing lists and add new lists. You increase the likelihood that your contacts will become irritated and mark your emails as spam. 

Loss of lists

When deleting and adding new contacts manually, you risk:
  1. Typos

  2. Missing out some email addresses 

  3. Adding data in the wrong format. 
These errors will have a direct impact on your business returns.

The best way to avoid the issues listed above is to have a consistent list. You can closely follow your contact base and avoid deliverability issues caused by incorrect list maintenance.
