How to skip a mailing?

[0xD7ba952CE8A0976e8d9852b7649bf01c30146]

I'm trying to skip a mailing when a condition I provide is false.
Please see the following code snippet:

  config.sequence :paid_onboarding do |seq|
    seq.title = "Paid Onboarding"
    seq.list = :paid_users
    seq.start_at = Proc.new { |user| user.account.subscription_end - 30.days } # days that have passed since subscription will be used in absolute_delay mailings below
    seq.enable

    # I WANT TO SKIP THIS MAILING FROM BEING SENT WHEN A CONDITION I PASS RETURNS FALSE
    # For example: Time.now < (user.account.subscription_end + 45.days)
    seq.mailing :subscription_ended_email_45 do |mailing|
      mailing.title = "Subscription ended 45 days ago"
      mailing.absolute_delay = 75.days
      mailing.mailer_name = "UserMailer"
      mailing.enable
    end
  end

Question: Is maily_herald capable of handle conditionals to determine whether or not an email must be sent?
If not, what other alternatives I have to accomplish my goal?

I know this is old, but someone is probably going to ask this too.

Take a look at how start_at is called, and create another method named skip_if(&block); if block true, skip.
