Nosto

If you’re looking for personalisation, Nosto is worth checking out, as an all-encompassing option that also handles things like retargeting and abandoned basket optimisation. Nosto sends a triggered email to abandoned cart users, giving you another chance to recover the sale. The customer then has the opportunity to continue their session, and actually complete the purchase. This is just a small part of what you can do with Nosto, but it’s worth it for the trigger emails alone.
