The link gives adequate instructions for addressing the envelopes but, what are the limitations for number of envelopes and per month, if any, please? Can we still send multiple month's worth of envelopes together for convenience of both parties?
Can anyone confirm how many envelopes you can be credited for in 1 month? I've asked regulars, private messaged Kimbr with no answer, and asked on forums but can't get an answer. Their T/C for this only say the amount ($5 / envelope) but do say what the limit is for envelopes per month per user.
