Invite them to an event at the local chapter for an open house. You can also promote a "Bring a non-XYZ" to a wine and cheese or happy hour. It can be really intimidating to go to an event alone, so always include non members, spouses, etc., if you can. You'll get your headcount up if nothing else and make it more welcoming. Also, instead of a welcome letter to new alumnae in the area, organize a phone tree and call them and invite them to a coffee hour with other alum. Even if it just 2 people, it's still coffee and they may feel more inclined to come to a future event.

If there is a collegiate chapter nearby, host a new member brunch for the new girls during their new member period. Co-host a membership education workshop with your AA and the chapter. Co-host a philanthropy event. Really integrate with chapter programming as much as possible. New alum are familiar with chapter life and are still clinging to it, so if they are new in town it is a little less scary to go to a chapter event than an AA-only event. Also, by hosting the combined chapter and AA events, you are grooming future alumnae members both for your AA and others.
