2nd paragraph

"If your SPF records are very long and complex, they may exceed the maximum length of a TXT record’s data, 255 bytes. In that case, you can break the record into multiple TXT records, each beginning with the v=spf1 tag. They’ll be concatenated before evaluation." This might be a trap. According to RFC4408 which defines the SPF specification, it says: 3.1.2. Multiple DNS Records A domain name MUST NOT have multiple records that would cause an authorization check to select more than one record. See Section 4.5 for the selection rules.
