The catchThere is no self-service way to cancel. You have to call their Billing Support line, and the moment the account closes you lose access to your contacts, campaigns and reports immediately, with only a 30-day window before an inactive account's data can be deleted for good.A smaller name with a smaller integration list.

Getting your list back out

Constant ContactHard to leave

There is no self-service cancel button. Their own help article says you have to call their Billing Support line, and once the account is cancelled you immediately lose access to your contacts, campaigns and reporting; images go offline and integrations disconnect. They only guarantee to store the account and its data for 30 days afterward, after which an inactive account's contacts and content may be permanently deleted. Source

SenderEasy to leave

The friendliest exit terms we found. Cancelling drops you to the free plan instead of deleting anything: their help page says subscribers, campaigns, automations, forms and reports are all retained. Source

Constant Contact vs Sender, answered

Is Constant Contact or Sender better for an online course?
Neither is better outright, and anyone who says so is guessing on your behalf. Sender if you are starting out with no budget. Sender if you are a list already in the thousands. Sender if you are worried about being locked in.
Which of Constant Contact and Sender has the better free plan?
Sender allows more free subscribers (2,500 against none). A bigger allowance is not automatically the better plan: check the welcome sequence row above, because that is where the two usually part company.
Can I move from Constant Contact to Sender later?
Yes, and you should assume you will. Export your list before you cancel anything, and keep whatever marks who bought from you. We wrote the whole running order up separately.
