Short answer. Yes, electronic mail is an expressly recognized mode. Section 5 of Rule 13 lists personal service, registered mail, accredited courier, electronic mail, facsimile transmission, other court-authorized electronic means, or modes under applicable international conventions as valid ways to serve pleadings and other court submissions.

What the law says

Pleadings, motions, notices, orders, judgments, and other court submissions shall be served personally or by registered mail, accredited courier, electronic mail, facsimile transmission, other electronic means as may be authorized by the [c]ourt, or as provided for in international conventions to which the Philippines is a party.

The full menu of service modes

Section 5 lists several recognized modes by which pleadings, motions, notices, orders, judgments, and other court submissions may be served: personally, by registered mail, by accredited courier, by electronic mail, by facsimile transmission, by other electronic means as may be authorized by the court, or as provided for in international conventions to which the Philippines is a party. This is a considerably more modern and flexible list than the traditional personal-service-or-mail dichotomy.

Electronic mail is expressly included

Notably, the section names electronic mail directly as an authorized mode alongside the more traditional methods, reflecting the current Rules' accommodation of digital practice. A party or counsel can validly serve pleadings and other covered documents by email under this section, without needing separate special court authorization for that particular mode, since it is already listed as one of the enumerated options.

Court-authorized 'other electronic means' as a catch-all

Beyond the specifically named modes, Section 5 leaves room for other electronic means as may be authorized by the court — a flexible catch-all that can accommodate service technologies or platforms not specifically enumerated, provided the court sanctions their use. The reference to international conventions also covers service in cases with a cross-border dimension, where the Philippines' treaty obligations may prescribe a particular method.

The modes apply across pleadings and other submissions alike

Section 5's list is not limited to the initiatory pleading or to motions alone; by its own terms it covers pleadings, motions, notices, orders, judgments, and other court submissions generally. That means the same menu of service modes, including electronic mail, is available throughout the life of a case, not just at the moment a complaint or answer is first filed and served. A party relying on email service for a motion filed mid-case is invoking the same authorization as a party who used it to serve the original complaint. That breadth matters because it means a party does not have to track a different set of permissible service methods for a motion versus a judgment versus a simple notice; the same menu of options in Section 5 governs all of them uniformly.
