MX Priority

Priority can be set for different email servers, with values ranging from 1–50. The smaller the value, the higher the priority.

Weight

When a domain is set with multiple records pointing to different addresses, you can distribute the proportion of each line's resolution through weights. The proportion resolved to a certain record: the weight of that record / the sum of the weights of all records for that subdomain.
